Question

Part A

Which of the following statements are true?

Check all that apply.

-The temperature of a gas sample is related to the average kinetic energy.

Part B

Which statements about a sample of gas containing molecules of different masses are true?

Check all that apply.

-The average speed of gas molecules is independent of temperature. -There are gas molecules that move slower than the average. -The average speed of gas molecules increases with increasing temperature. -The average kinetic energy of gas molecules decreases with decreasing temperature.

-The temperature of a gas sample is related to the average kinetic energy.

Part B

Which statements about a sample of gas containing molecules of different masses are true?

Check all that apply.

- More-massive gas molecules in the sample have lower rms speed than less-massive ones. -The rms speed depends only on temperature, and so all types of particles in the sample have the same rms speed. -More-massive gas molecules in the sample have higher rms speed than less-massive ones.
