The internal energy (U) of an ideal gas decreases by the same amount as the work done by the system:

During the adiabatic expansion of 2 moles of a gas, the internal energy of the gas is found to decrease by 2 joules , the work done during the process on the gas will be equal to

In an isobaric process of an ideal gas. The ratio of heat supplied annd work done by the system [i.e.,((Q)/(W))] is

550 kJ "cycle" ^(-1) work is done by 1 mol of an ideal gas in a cyclic process. The amount of heat absorbed by the system in one cycle is

During the adiabatic expansion of 2 moles of a gas, the internal energy was found to have decreased by 100 J . The work done by the gas in this process is

Assertion: If a gas is heated isothennally, then no part of the heat supplied is used to increase the internal energy. Reason: Change in internal energy equals work done on the system.
