Question

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`

Answer 1

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