Question 645: Thermodynamics & KTG

Question

In a cyclic process, work done by the system is

Accepted Answer

In a cyclic process, the system returns to its initial state. According to the first law of thermodynamics,
$$ \Delta U = Q - W $$
where $\Delta U$ is the change in internal energy, $Q$ is the heat given to the system, and $W$ is the work done by the system.
For a cyclic process:
The system returns to its original state, so $ \Delta U = 0 $.
So,
$$ 0 = Q - W \implies Q = W $$
Correct answer:
Option B: equal to the heat given to the system.

Answer

more than the heat given to the system.

Answer

equal to the heat given to the system.

Answer

zero.

Answer

independent of the heat given to the system.
