Equal mass of the helium and oxygen gases are given equal quantities of heat. Which gas will undergo a greater temperature rise?

Explanation

The helium gas will undergo a greater temperature rise. The reason is as follows: helium is a monatomic gas while oxygen is a diatomic gas. .The heat given to helium will be totally used up in increasing the translational kinetic energy of its molecules, where as the heat given to oxygen will be used up in increasing the translation kinetic energy of the molecules as well as in increasing the , kinetic energy of ratation and vibration
