- for Ideal gas under different pathway

- Relevant Equations
- E = Q+W

PV = nRT

Question: Two samples of a monatomic ideal gas are in separate containers at the same conditions of pressure, volume, and temperature (V = 1.00 L and P = 1.00 atm). Both samples undergo changes in conditions and finish with V = 2.00 L and P = 2.00 atm. However, in the first sample, the volume is changed to 2.0 L while the pressure is kept constant, and then the pressure is increased to 2.00 atm while the volume remains constant. In the second sample, the opposite is done. The pressure is increased first, with constant volume, and then the volume is increased under constant pressure. Calculate the difference in delta E between the first sample and the second sample.

for sample 1 is calculated by W = W1 +W2 = p1 delta(V) +0 = L atm, and for sample 2 W = 0+P2 deltaV = -2 L atm. But I have no idea how to calculate the Q for each samples.
