MHT CET 2026 Physics question

A thermodynamic system is compressed adiabatically, then its temperature

(A)becomes zero.
(B)remains constant.
(C)increasesCorrect
(D)decreases.

Answer: (C)

Solution

In an adiabatic process , so by the first law , where is the work done by the system. During compression the surroundings do work on the system (), so . The internal energy of a gas depends on temperature ($Δ U =
