An isolated gas (nitrogen, N2), at initial temperature of 22.7 degrees Celsius, is expanded from as initial volume of 0.750L to 1.450L at constant pressure, P=132kPa. During this process the gas absorbs 318.5J of heat.

i. Calculate the work output by the system during this expansion

ii. Estimate the specific heat capacity of the gas for this process. Express your answer in J/kg*K.
