Calculate Q and w for the isothermal reversible expansion of one mole an ideal gas from an initial pressure of 1.0 bar to a final pressure of 0.1 bar at a constant temperature of 273 K respectively.

A

5.22kJ, -5.22 kJ

B

`-5.22 kJ, 5.22 kJ`

C

27.3 kJ, -27.3 kJ

D

`-27.3 kJ, 27.3 kJ`

Text Solution

Verified by Experts

The correct Answer is:
A

In isothermal process change in internal energy is 0, so `q = -w`
