What is the average kinetic energy (in J) of helium atoms in a region of the solar corona where the temperature is 5.70 ✕ 10^5 K?

Answer:

Heat, which is the exchange of energy between a system and its surroundings, occurs in three major ways: conduction, convection and radiation.

Which has higher heat capacity oil or water?

For both the hot plate and the microwave, olive oil will heat up faster than water because the heat capacity of oil is lower than the heat capacity of water. Water requires more energy per gram of liquid to change its temperature.

when I search I found this answer I hope it can help you answer your question.

Answer:

The temperature rises because for a given volume of gas, a rise pressure of the gas in pressure results in a proportionate rise in the temperature of the gas

Similarly when the handle is raised to draw air causes a fall in pressure that results in proportionate fall in temperature, for a given volume of gas

Explanation:

From Gay-Lussac's law, states that the pressure of a given mass of gas is directly proportional to its Kelvin temperature, provided that the volume is held constant

Mathematically, the law states that Pressure ∝  Temperature, at constant Volume

Therefore;

P₁/T₁ = P₂/T₂

Similarly, by kinetic theory of gases, we have;

The

\(P = \dfrac{n \cdot MW \cdot v_{rms}^2}{3 \cdot V}\)

\(v_{rms} = \sqrt{\dfrac{3 \cdot R \cdot T}{MW} }\)

Therefore, as in order for the hand pump to inflate the bicycle tires, the air in the pump has to be compressed to force it into the tire, thereby increasing the pressure, of the air in a given volume of the pump which results in the raising of the temperature of the air in the pump, which raises the temperature of the wall of the pump.

The temperature of the air in the pump also falls as the pressure in the pump is reduced by raising the pump handle, to reduce the air pressure inside the pump and and allow air to be taken into the pump.

Answer:

Explanation:

vapour pressure at 70⁰F = .36 psi

pressure of 6.5 inch water column

6.5 inch = 6.5 x 2.54 cm =.165 m

pressure = .165 x 10³ x 9.8 = 1617 Pa

= 1617 x .000145 psi

= .23 psi

28.35 inch = 28.35 x 2.54 cm = .72 m

pressure = .72 x 13.6 x 10³ x 9.8

= 95961.6 Pa

= 95961.6 x .000145 psi

= 13.91 psi

a ) Barometric pressure at  70⁰F

=  pressure due to mercury column of 28.35 inch + water column of 6.5 inch + vapour pressure at 70⁰F

= 13.91 + .23 + .36 psi

= 14.5 psi

If pressure is measured at 85⁰F

vapour pressure will be increased and pressure of dry gas will also be increased . This pressure will force down the column of mercury . So column of mercury will go down .

 a. The function that describes the oscillations of the object can be described using a sinusoidal function.

b. Yes, the function is shifted in the x-direction.

c. No, the function is not squeezed or stretched along the y-axis.

d. No, the function is not squeezed or stretched along the x-direction. The equation describing the position of the object in time can be expressed as :x(t) = A * cos(ωt + φ)

e. x(0) = A * cos(ω * 0 + φ) = 2 is the equation describing position of the object in time.

a. The function that describes the oscillations of the object can be described using a sinusoidal function. A common function used to represent oscillatory motion is the cosine function or the sine function. In this case, since the object is in the equilibrium position at t=0 and t=2s, we can use the cosine function to describe its oscillations.

b. Yes, the function is shifted in the x-direction. The equilibrium position of the object is at x=2m, which means the function is shifted 2 units to the right along the x-axis.

c. No, the function is not squeezed or stretched along the y-axis. The amplitude of the oscillations remains constant at 0.2 m.

d. No, the function is not squeezed or stretched along the x-direction. The period of the oscillations remains constant, indicating that the function is not compressed or stretched along the x-axis.

The equation describing the position of the object in time can be expressed as follows:

x(t) = A * cos(ωt + φ)

Where:

- x(t) represents the position of the object at time t.

- A is the amplitude of the oscillations (0.2 m in this case).

- ω is the angular frequency, given by ω = 2π / T, where T is the period of oscillation.

- φ is the phase constant, representing the initial phase of the oscillation.

e. To determine the equation describing the position of the object in time, we need to find the values of ω and φ. Since the object is in the equilibrium position at t=0 and t=2s, we can use this information to determine the values.

At t=0, the object is in the equilibrium position, so we have:

x(0) = A * cos(0 + φ) = 2

At t=2s, the object is in the equilibrium position again, so we have:

x(2) = A * cos(2ω + φ) = 2

Now,

At t=0, we have:

x(0) = A * cos(ω * 0 + φ) = 2

in this case v = 9.5 m / s the mass of the drone is m = 11 kg.

The distance can therefore be found using the Pythagorean theorem, but we can see that the relation

           r_perpendicular = r sin θ

           r_perpendicular = 25 m

as the flight is horizontal this height does not change

           L = m v r_perpendicular

The increase in the blood pressure in the patient's arm will be 11433.55 Pascal.

The power with which your heart pumps blood around your body is measured by your blood pressure. Blood pressure is expressed as two values in millimeters of mercury.

The given data in the problem is;

\(\rm V_1 = V_2\)

\(\rho\) is the density =  1050 \(Kg /m^3\)

h is the level of height higher than the level of a patient's arm = 1.00 m

From the Bernoullis equation the difference in pressure between the two points is found as;

\(P_1+0.5 \times \rho \times {V_1}^2+ \rho g h_1=P_2+0.5 \rho \times V_2 ^2 + \rho \times g \timews h_2\)

\(\rm V_1 = V_2\)

\(\rm P_2-P_1 = 1050 \times g \times (h_1-h_2) \\\\ \rm P_2-P_1 = 1050 \times 9.81 \times (1.11) \\\\ \rm P_2-P_1 =11433.55 \ Paacal\)

Hence the increase in the blood pressure in the patient's arm will be 11433.55 Pascal.

According to the Keynesian view, manipulating foreign sector spending is not a reliable way to move the U.S. economy toward a more acceptable equilibrium because it does not address the fundamental causes of economic instability.

Keynesian economics focuses on the role of domestic demand in driving economic growth and stability. The government can use fiscal and monetary policy to stimulate aggregate demand and promote full employment. However, changes in foreign sector spending can be unpredictable and beyond the control of domestic policymakers. For instance, an increase in foreign demand for U.S. exports could boost economic growth and employment in the short run, but it may not be sustainable if the foreign demand later decreases. Similarly, a decrease in foreign demand for U.S. exports could have negative short-term effects on the economy, but it may not necessarily lead to a long-term decline. In short, Keynesian economics emphasizes the importance of domestic demand management and stabilizing the economy through government intervention. While changes in foreign sector spending can have some impact on the economy, they are generally seen as unreliable and unpredictable, and therefore not a reliable tool for achieving economic stability in the long run.

The heat energy required to change a 0.3 kg ice cube from a solid at -20 °C to steam at 120 ℃ is 915.78 kJ.

The process of changing a 0.3 kg ice cube from solid at -20 ℃ to steam at 120 ℃ involves the following steps:

1. First, the ice cube must be warmed from -20 ℃ to 0 ℃.

The quantity of heat required can be calculated using the formula Q = mcΔT, where Q is the heat required, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

Since the ice is at a constant temperature, ΔT is equal to 0.

Hence, no heat is required to change the temperature of the ice cube from -20 ℃ to 0 ℃.

2. Second, the ice cube must be melted at 0 ℃.

The heat required to melt the ice cube can be calculated using the formula Q = mL, where Q is the heat required, m is the mass of the substance, and L is the latent heat of fusion of the substance.

For water, the latent heat of fusion is 334 J/g.

Hence, the heat required to melt the 0.3 kg ice cube is 0.3 kg x 334 J/g = 100.2 kJ.

3. Third, the liquid water must be warmed from 0 ℃ to 100 ℃.

The quantity of heat required can be calculated using the formula Q = mcΔT, where Q is the heat required, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

For water, the specific heat capacity is 4.184 J/g℃.

Hence, the heat required to warm the 0.3 kg of liquid water from 0 ℃ to 100 ℃ is 0.3 kg x 4.184 J/g℃ x 100 ℃ = 125.52 kJ.

4. Fourth, the liquid water must be boiled at 100 ℃ to form steam at 100 ℃.

The heat required to boil the liquid water can be calculated using the formula Q = mL, where Q is the heat required, m is the mass of the substance, and L is the latent heat of vaporization of the substance.

For water, the latent heat of vaporization is 2260 J/g.

Hence, the heat required to boil the 0.3 kg of liquid water is 0.3 kg x 2260 J/g = 678 kJ.

5. Fifth, the steam must be heated from 100 ℃ to 120 ℃.

The quantity of heat required can be calculated using the formula Q = mcΔT, where Q is the heat required, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

For steam, the specific heat capacity is 2.010 J/g℃.

Hence, the heat required to heat the 0.3 kg of steam from 100 ℃ to 120 ℃ is 0.3 kg x 2.010 J/g℃ x 20 ℃ = 12.06 kJ.6.

The total heat required to change the 0.3 kg ice cube from solid at -20 ℃ to steam at 120 ℃ is the sum of the heat required for each step.

Hence, the total heat required is 100.2 kJ + 125.52 kJ + 678 kJ + 12.06 kJ = 915.78 kJ.

Therefore, the heat energy required to change a 0.3 kg ice cube from a solid at -20 °C to steam at 120 °℃ is 915.78 kJ.

Answer:

The vibrating length of the air column is greater than the actual length of the organ pipe

The work done by the gas during the isothermal expansion is 421 J, and the heat added to the gas during the isothermal expansion is 421 J.

Isothermal expansion refers to a thermodynamic process in which a gas expands at a constant temperature. During this process, the gas absorbs heat from its surroundings, which is converted into work done by the gas as it expands. The pressure and volume of the gas change, but the temperature remains constant throughout the process.

1. We can use the ideal gas law and the formula for work done in isothermal expansion to solve this problem:

The work done by the gas during the isothermal expansion is given by:

W = nRT ln(V2/V1)

where W is the work done, n is the number of moles of gas, R is the gas constant, T is the temperature, V1 is the initial volume, and V2 is the final volume.

Since the process is isothermal, the temperature remains constant, so we can simplify the equation to:

W = nRT ln(V2/V1)

We can find n by using the ideal gas law:

PV = nRT

where P is the pressure, V is the volume, and T is the temperature.

Solving for n, we get:

n = PV/RT

Substituting the given values, we get:

n = (8 kPa x 6 L) / (8.31 J/mol·K x 273 K)

n = 0.164 mol

Now we can calculate the work done:

W = nRT ln(V2/V1)

W = (0.164 mol)(8.31 J/mol·K)(273 K) ln(8 L / 6 L)

W = 421 J

Therefore, the work done by the gas during the isothermal expansion is 421 J.

2. Since the process is isothermal, the temperature remains constant and the change in internal energy is zero. So, the heat added to the gas is equal to the work done on the gas:

Q = W

Q = 421 J

So, the heat added to the gas during the isothermal expansion is 421 J.

Therefore, The gas expands 421 J of work during isothermal expansion, and the gas absorbs 421 J of heat during the process.
