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.
