During the compression stroke of a certain gasoline engine, the pressure increases from 1.00 atm to 20.3 atm. Assume that the process is adiabatic and the gas is ideal with (gamma)= 1.40.
(a) By what factor does the volume change?
Vfinal = (ans)*Vinitial
(b) By what factor does the temperature change (when expressed using an absolute scale)?
Tfinal =(ans) * Tinitial
(c) If the compression starts with 0.0160 mole of gas at 27.5°C, find the values of Q, W, and Eint that characterize the process.
I know the relationship is described by PV^(gamma)=constant but am clueless on how to apply this to get the answers.
