Question 03: State and explain the first law of thermodynamics.

Answer:

First Law of Thermodynamics: In all transformation, the amount of heat supplied to a system must be balanced by the sum of the gain in the internal energy of the system due to the rise in temperature and the work done.

So, we can write
dQ = dU +\frac{dW}{J}

Where,

dQ = Heat supplied

dU = Change in internal energy

\huge \frac{dW}{J}=Heat equivalent of the work done.
