When heat energy of 1500 J is supplied to a gas at constant pressure , 2.1 xx 10^(5) Nm^(-2) , there was an increase in its volume equal to 2.5 xx 10^(-3) m^(3). The increase in its internal energy in joule is

A gas absorbs 100 J of heat and is simultaneously compressed by a constant external pressure of 1.5 atm from a volume of 8.0L to 2.0L. The change in internal energy for the gas in Joules is (1L - atm = 101.32 J))

A gas under constant pressure of 4.5 xx 10^5 Pa when subjected to 800 kJ of heat, changes the volume from 0.5m^3 to 2.0 m^2 . The change in internal energy of the gas is:

One kg of a diatomic gas is at a pressure of 8 xx 10^4 N//m^2 . The density of the gas is 4kg/m^3 . What is the energy of the gas due to its thermal motion?
