Answer 1

Explanation:

a

TWO moles of

an ideal gas

undergoes adiabatic expansion

against

constant external

pressure. The work involved in the

process is equal to 30 kJ. The

temperature of the gas decreases

by 50 K during the process. Heat

capacity of the gas is equal to

12.4718 J K moll. The change in

molar internal energy of the gas

during the process is equal to

A. 21.2359 kJ mol-1

B. 42.4718 kJ mol-1

O C. 15 kJ mol-1

OD. 30 kJ mol-1
