Change in internal energy = 216.5J
Explanation:
according to kinetic theory of gases
change in internal energy of a ideal gas is directly proportional to temperature change.
As mentioned above temperature change = 600K
gas is mono-atomic
no. of moles = 2
Change in internal energy = (number of moles ) (specific heat at constant volume) (temperature change)
ΔU = nΔT
(for mono - atomic gases)
change in internal energy = 2×600 ×
=1800÷ 8.314
ΔU = 216.5J
