1 mole of an ideal gas A (Cv,m = 3 R) and 2 mole of an ideal gas B \(\left(\mathrm{C}_{\mathrm{v}, \mathrm{~m}}=\frac{3}{2} \mathrm{R}\right)\) are taken in a container and expanded reversibly and adiabatically from 1 litre to 4 litre starting from initial temperature of 320 K. ∆E or ∆U for the process is :
- –240 R
- 240 R
- 480 R
- –960 R
Answer
(D) –960 R
