104 kj of work is done on certain volume of a gas. If the gas releases 125 kj of heat, calculate the change in internal energy (in kj) of the gas.

no work is done against gas.

A System absorbs 520J of heat and perform work of 210J calculate the change in internal energy.

A system releases 125 kj of heat while 104 kj of work done on the system. Calculate the change in internal energy.

5 KL of work is done on the system and it releases 10 kJ of heat. What is DeltaU ?

In an adiabatic process 90 J of work is done on the gas. The change in internal energy of the gas is

In a thermodynamic process , pressure of a fixed mass of a gas is changed in such a manner that the gas releases 20J of heat and 8J of work is done on the gas. If the initial internal energy of the gas was 30J . The final internal energy will be

25 KJ work is done on the system and it releases 10 KJ of heat what is DeltaU ?
