Three moles of an ideal gas (CP,m = 2.5R) and 2 moles of another ideal gas (CP,m = 3.5R) are taken in a vessel and compressed reversibly and adiabatically. In this process, the temperature of gaseous mixture increased from 300 K to 400 K. The increase in internal energy of gaseous mixture (in cal) is Backspace 78 9 4 5 6
