S_(1) : "All collisions between the molecules of the gas and walls of container are elastic". This assumption has validity only when temperature of both, the gas and the walls of the container, are same S_(2) : If DeltaV=0 in a process then work done by the gas must be zero. (T/F) S_(3) : Internal energy of one kilogram of Helium is same as that of one kilogram of Argon at the same temperature.
