A perfect gas goes from state A to another state B by absorbing 8 x 10^5 J of heat and doing 6.5 x 10^5 J of external work. It is now transferred between the same two states in another process in which it absorbs 10^5 J of heat. Then in the second process,

A certain mass of is taken from an initial thermodynamics state A to another state B by process I and II. In process I for the gas does 5 J of work and absorbs 4 J of heat energy. In process II, the gas absorbs 5 J of heat. The work done by the gas in process II is

A gas undergoes change from state A to state B. In this process, the heat absorbed and work done by the gas is 5 J and 8 J, respectively. Now gas is brought back to A by another process during which 3 J of heat is evolved. In this reverse process of B to A:

600J of heat is added to a monoatomic gas in a process in which the gas performs a work of 150J. The molar heat capacity for the process is

When a gas is taken from one state a to another state b via one path, it absorbs 25 calories of heat while doing 70J of work. How much heat much heat has to be supplied in taking the same gas from state a to state b via another path when it performs 200J of work?

A gas absorbs 100 Calorie of heat and performs 150J of work. Increase energy of the gas in the process is

"600J" of heat is added to a monatomic gas in a process in which the gas performs a work of "150J" .The molar specific heat capacity of the gas for the process is

when a system is taken through the process abc shown in 80 J of heat is absorbed by the system and 30 J of work is done by it. If the system does 10 J work during the process adc, how much heat flows into it during the process ?

A gas undergoes a change of state during which 100J of heat is supplied to it and it does 20J of work. The system is brough back to its original state through a process during which 20 J of heat is released by the gas. What is the work done by the gas in the second process?
