Question

Which of the following statements are true?

Check all that apply.

There are gas molecules that move slower than the average.

All the gas molecules in a sample have the same kinetic energy.

There are gas molecules that move faster than the average.

The average speed of gas molecules increases with temperature.

The average kinetic energy of gas molecules increases with temperature.

What are each of the following observations an example of?

Drag the appropriate items to their respective bins.

A balloon in a constant environment gets smaller and smaller over the course of a week. There is a gas leak in the kitchen and you smell gas in the bedroom after 10 minutes. Diffusion Effusion Fusion Diffraction Refraction Which statements about a sample of gas containing molecules of different masses are true? Check all that apply. View Available Hint(s) Check all that apply. 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 lower rms speed than less-massive ones. More-massive gas molecules in the sample have higher rms speed than less-massive ones.
