A 2.20-mol sample of helium gas initially at 300 K, and 0.400 atm is compressed isothermally to 1.00 atm. Note that the helium behaves as an ideal gas.
(a) Find the final volume of the gas. express answer in m^3
(b) Find the work done on the gas. express answer in kJ
(c) Find the energy transferred by heat. express answer in kJ
