Two identical, sealed, and well-insulated jars contain different gases at the same temperature. each container contains the same number of moles of gas. container 1 contains helium, a monotomic gas with a molecular weight of 4.0 kg / kmol. container 2 contains co2 , a triatomic linear molecule with a molecular weight of 44 kg / kmol.

(a) which gas has higher internal energy?

(b) which gas has higher translational energy?

(c) which gas has higher pressure?
