Here is your answer


The first law of thermodynamics states that the total heat energy given to an isolated system is partially use to increase the internal energy of the system and partially use to do work against external pressure.


According to the above statement, we have

dQ = dU + dW

This the mathematical expression for the first law of thermodynamics.
