Two moles of Helium gas 
are initially at temperature 
and occupy a volume of 20 liters. The gas is first expanded at constant pressure until the volume is doubled. Then it undergoes an adiabatic change until the temperature returns to its initial value.
What is the work done by the gas? (Gas constant 
mole K)
Text Solution
Verified by ExpertsThe correct answer is:
D
The work done by gas in isobaric process 
The work done by gas during adiabatic process BC
.
