Case Study Questions on Thermodynamics

Passage:
The first law of thermodynamics is essentially a restatement of the law of conservation of energy. It is written as:

$$
\Delta U=Q-W
$$

Where:
– $\Delta U=$ change in internal energy
– $Q=$ heat supplied to the system
– $W=$ work done by the system

A student performs an experiment where no work is done, but heat is supplied.

Q1. If no work is done and heat is added, what happens to internal energy?
(a) Remains constant
(b) Decreases
(c) Increases
(d) Becomes zero

Answer: (c)

Q2. If heat is extracted from the system with no work done, what will be ΔU\Delta UΔU?
(a) Negative
(b) Zero
(c) Positive
(d) Infinite

Answer: (a)

Q3. Which of the following is a state function?
(a) Work
(b) Heat
(c) Internal energy
(d) Path taken

Answer: (c)
Explanation:
Internal energy depends only on the initial and final states, not on the path → state function

Q4. What does the first law imply?
(a) Energy is destroyed
(b) Work creates mass
(c) Energy is conserved in all processes
(d) Heat is path-independent

Answer: (c)
Explanation:
Total energy remains constant → heat supplied = internal energy change + work done.

We hope the given case study questions for Thermodynamics Class 11 helps you in your learning.
