Homework Statement
A 3000 cm3 container holds 0.10 mol of helium gas at 300C.
How much work must be done to compress the gas to 1000 cm3 at constant pressure?
How much work must be done to compress the gas to 1000 cm3 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
apparently Mastering physics thinks this is neither here nor there, well, I am very
