Common Thermodynamic Processes
Isothermal
- • Constant temperature
- • PV = constant
- • Slow process
- • ΔU = 0
Adiabatic
- • No heat transfer
- • PVγ = constant
- • Fast process
- • Q = 0
Isobaric
- • Constant pressure
- • V/T = constant
- • W = PΔV
- • Common in gases
Isochoric
- • Constant volume
- • P/T = constant
- • W = 0
- • ΔU = Q
