One mole of a monatomic ideal gas is taken through a reversible process from an initial state "a" to a final state "b" during which the pressure of the gas varies with volume V as shown below. Calculate the work Won[/on](a->b) done on the gas during this process.
problem shows a graph which i'll just write out points a and b
a = (300kPa, 1m^3), b= (500kPa, 2m^3)
The Attempt at a Solution
work on = negative integral Pextdv and since this is reversible then P should equal Pext
I can calculate the temp at a and b, but i don't think that will contribute to anything.
Sorry this should be easy, but i'm confused
