In a thermodynamic system,internal energy decreases by 300J when it is doing 350J of work.What net heat is taken by system in the process?

In thermodynamic system internal energy decreases by 400 J while it is doing 250J of work.What net heat is taken in by the system in the process.

Heat equivalent to 50 joule is supplied to a thermodynamic system and 10 joule work is done on the system. What is the change in the internal energy of the system in the process ?

A system gives out 30 J of heat and also does 40 J of work. What is the internal energy change?

What is the internal energy of the system, when the amount of heat Q is added to the system and the system does not do any work during the process?

A system absorbs 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?

For a gaseous system find change in internal energy if the heat supplied to the system is 50 J and work done by the system is 16 J.

A system absorbs reversibly 600 J of heat and performs 250 J of work. The increase in the internal energy of system is :-

A system gives out 20 J of heat and also does 40 J of work. What is the internal energy change?

A system gives out 30 J of heat and does 75 J of work. What is the internal energy change?
