Physics Chapter 4: Thermodynamics Flashcards
1
Q
Heat engine efficiency
A
= W/Qh, where W = Qh - Qc
Efficiency = total work divided by heat input
2
Q
adiabatic compression
A
NO HEAT exchange with the surroundings, meaning the gas heats up.
adiabatic compression = heats up
adiabatic expansion = cools off
