Assignment Help:

First Law for closed system undergoing cycle:

In accordance to first law, when a closed system undergoes thermodynamic cycle, the net heat transfer is equal to network transfer. The integral of heat transfer is equal to the cyclic integral of work transfer.

Ñ dQ = Ñ dW .

here Ñ stands for cyclic integral (integral around the complete cycle), dQ and dW are small elements of heat and work transfer and are having same units.
