A closed system receives 200kJ of heat at constant volume. It then rejects 100kJ of heat while it has 50kJ of work done on it at constant pressure. If an adiabatic process can be found which will restore the system to its initial state, the work done by the system during this process is

consider the processes on a system shown in. during the processes,the work done by the system

A perfect gas undergoes the following three separate and distinct process to execute a cycle i)constant volume process during which 80 kJ of heat is supplied to the gas. ii) constant pressure process during which 85 kJ of heat is lost to the surroundings and 20 kJ of work is done on it. iii) adiablatic process which restores the gas back to its initial stage. Evaluate the work done during adiabatic process and the value of internal energy at all the state points if initially its value is 95 kJ.

A system undregoes a change of state during which 100kJ of heat is transferred to it and it does 50kJ of work. The system is brought back to its original state through a process during which 120kJ of heat is transferred to it. Find the work done by the system in the second process.

A system releases 100 kJ of heat while 80 kJ of work is done on the system. Calculate the change in internal energy.
