During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 20.0 atm. If the process is adiabatic and the air–fuel mixture behaves as a diatomic ideal gas, (a) by what factor does the volume change and (b) by what factor does the temperature change? Assuming the compression starts with 0.016 0 mol of gas at 27.0°C, find the values of (c) Q, (d) ΔEint, and (e) W that characterize the process.
The PV diagram in the figure below shows a set of thermodynamic processes that make up a cycle ABCDA for a monatomic gas, where AB is an isothermal expansion occurring at a temperature of 355 K. There are 1.35 mol of gas undergoing the cycle with PA = 1.01 ✕ 106 Pa, PB = 5.10 ✕ 105 Pa, and PC = 2.02 ✕ 105 Pa.
