Heat and Thermodynamics question

2025 · 24 Jan · Shift 2 · Q61

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : In an insulated container, a gas is adiabatically shrunk to half of its initial volume. The temperature of the gas decreases. Reason (R) : Free expansion of an ideal gas is an irreversible and an adiabatic process. In the light of the above statements, choose the correct answer from the options given below :
  1. A
    Both (A)(\mathbf{A})(A) and (R)(\mathbf{R})(R) are true and (R)(\mathbf{R})(R) is the correct explanation of (A)(\mathbf{A})(A)
  2. B
    Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
  3. C
    (A) is false but (R) is true
  4. D
    (A) is true but (R)(\mathbf{R})(R) is false
