Question

During adiabatic compression of a gas, its temperature ___________

(a) Falls

(b) Remains constant

(c) Rises

(d) Becomes zero

I had been asked this question in a job interview.

Question is taken from Specific Heat and Thermodynamics in section Kinetic Theory of Gases of Engineering Physics I

Answer 1

Right answer is (c) Rises

To explain: The work done on the gas during the adiabatic process increases its internal energy and hence its temperature rises.
