Calculation:

In an isothermal process, the temperature of the system remains constant. According to the first law of thermodynamics:

ΔU = Q - W

Where:

ΔU is the change in internal energy

Q is the heat absorbed by the system

W is the work done by the system

For an isothermal process, the change in internal energy (ΔU) is zero because the temperature does not change. Thus:

ΔU = 0

Therefore, the heat given to the system (Q) is entirely converted into work done by the system (W). Hence, in an isothermal process:

Q = W

Thus, the correct answer is Option 2: net work done by the system.
