Question 10

A rigid container of volume V V\,V contains a trapped monatomic ideal gas of total mass MMM. The pressure of the gas is p p\,p and the mass of a single atom of the gas is mmm.

Which of the following expressions gives the average translational kinetic energy of a single atom of this gas?
