Heat and Thermodynamics question

2025 · 29 Jan · Shift 2 · Q55

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) : With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process. Reason (R) : In isothermal process, PV = constant, while in adiabatic process PVγPV^{\gamma}PVγ= constant. Here γ\gammaγ is the ratio of specific heats, P is the pressure and V is the volume of the ideal gas. In the light of the above statements, choose the correct answer from the options given below:
  1. A
    (A) is true but (R) is false
  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
    Both (A) and (R) are true and (R) is the correct explanation of (A)
