1. The problem statement,
During the compression stroke of a certain gasoline engine, the pressure increases from 1 atm to 20 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?
when i searched on the internet for Cv and Cp for diatmoic gas i found it to be 5/2 R
and i don't know why they consider the transitional and rotational motion only for the degree of freedoms and why they neglect the vibration motion i think it should be 7/2 R for Cv and 9/2 R for Cp
