When the temperature of a gas in a vessel is increased by 1C then the pressure is increased by 0.5%. what will be its initial temperature?

When an ideal diatomic gas is heated at constant pressure then what fraction of heat given is used to increase internal energy of gas?

In changing the state of a system from state A to state B adiabatically the work done on the system is 322 J. If 100 cal f heat are given to the system in bringing it from state A to state B, then what will be the work done on the system in this process?
