Question
A cylindrical tube of cross-sectional area A has two air tight frictionless pistons at its two ends. The pistons are tied with a straight two ends. The pistons are tied with a straight piece of metallic wire. The tube contains a gas at atmospheric pressure P0 and temperature T0 . If temperature of the gas is doubled then the tension in the wire is
- 4 P0 A
- P0A/2
- P0 A
- 2 P0 A
The correct answer is: P0 A
