Homework Statement
. Suppose a monatomic ideal gas is changed from state A to state D by one of the processes shown on the PV diagram below, in which each interval on the vertical (P) axis corresponds to 2 atm, and the values of the lines on the horizontal (V) axis equal 1 L, 2 L, and 4 L.
Graph attached.
(a) Find the total work done on the gas if it follows the constant volume path AB followed by the constant pressure path BCD.
(b) Find the total change in internal energy and total heat flow into the gas.
Homework Equations
For isotherm W = nRt (ln (Vf/Vi)
PV = nRT
The Attempt at a Solution
From A to B to C is an isotherm. Use equation above but substitute PV for nRT for either A or C as they are the same  got 255.6 J. Then add in PdeltaV for C to D as on 2 different isotherms. Total work = A to C isotherm work plus C to D work = 655.6. HELP!
