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

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

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.

Work done by the system on surroundings is :

In a particular reaction 2kJ of heat is released from the system and 8kJ of work is done on the system. What are changes in internal energy and enthalpy of system?

In a particular reaction 2kJ of heat is released by the system and 6kJ of work is done on the system. Determine DeltaH and DeltaU ?

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
