NCERT Class 11 Physics Chapter 4 Thermodynamics Test Mock Test
This free online test covers Chapter 4, Thermodynamics, from the NCERT Class 11 Physics Part II textbook. The 28 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.While boring a brass cannon in 1798, Benjamin Thomson (Count Rumford) found that the amount of heat produced depended on:
- AThe temperature of the surroundings in which the cannon was bored
- BThe sharpness of the drill, and not on the work done in turning it
- CThe number of pores in the brass from which the heat fluid could be scooped out
- DThe work done in turning the drill, and not on the sharpness of the drill
Q2.How does the thermodynamic description of a gas differ from a microscopic one or from that of kinetic theory?
- AIt specifies the co-ordinates and velocities of the huge number of molecules constituting the gas
- BIt specifies the distribution of molecular velocities without following individual molecules
- CIt avoids the molecular description altogether and specifies the state by macroscopic variables such as pressure, volume, temperature, mass and composition
- DIt specifies the net external force and torque acting on the gas as a whole
Q3.In thermodynamics, the state of a system is called an equilibrium state when:
- AThe net external force and the net external torque on the system are zero
- BThe macroscopic variables that characterise the system do not change in time
- CThe microscopic constituents of the system have all come to rest
- DThe system is losing heat to its surroundings at a steady rate
