A total of 27.1 kJ of heat energy is added to a 7.13 L sample of helium at 0.985 atm. The gas is allowed to expand against a fixed external pressure to a volume of 20.3 L .

Calculate the work done on or by the helium gas in units of joules, J.

What is the change in the helium's internal energy in units of kilojoules, kJ?
