The gas law (PV/T) = constant is true for

A

isothermal change only

B

adiabatic change only

C

both isothermal & adiabatic changes

D

neither isothermal nor adiabatic change.

Text Solution

Verified by Experts

The correct Answer is:
C
As PV=nRT
for n =constant : `((PV)/T)` =constant
for all change hence (2)
