A 3000 cm^{3}container holds 0.10 mol of helium gas at 300C.

How much work must be done to compress the gas to 1000 cm^{3}at constant pressure?

How much work must be done to compress the gas to 1000 cm^{3}at constant temperature?

The attempt at a solution

W = integration p dv

For constant pressure,

because pressure is constant, therefore it matters not what integral it is on

W= p = nRT/v = 0.1*8.314*573.15/3 = 158.34

For constant temperature,

W= integration p dv over integral v=1L and v=3L

W= 317.6
