Q. Statement I : : In isothermal process whole of the heat energy supplied to the body is converted into internal energy.
Statement II: According to the first law of thermodynamics $\Delta Q = \Delta U$ for an isothermal process.

Thermodynamics

Solution:

In isothermal process, $\Delta T=0$ and so $\Delta U=0$. Thus $Q=0+W=W$.
