In an isothermal process the volume of an ideal gas is halved. One can say that

A

Internal energy of the system decreases

B

Work done by the gas is positive

C

Work done by the gas is negative

D

Internal energy of the system increases

Text Solution

Verified by Experts

The correct Answer is:
C
As `Delta U =0`,
`Delta W=n R T In ((V_2)/(V_1))`
As `V_2=(V_1)/(2), Delta W rarr ` -ve
