Question

Which statement is false?

The average kinetic energies of molecules from samples of different “ideal” gases is the same at the same temperature.


Molecules of a gas undergo many collisions with each other and the container walls.


All molecules of an ideal gas have the same kinetic energy at constant temperature.


Molecules of greater mass have a lower average speed than those of less mass at the same temperature.

Answer 1

I would go with c as the false statement.
