WebMay 13, 2024 · The quantity (v1 / v2) is the ratio of the volume at state 1 and state 2 and is called the compression ratio. For v2 less than v1, the pressure p2 is greater than p1. With … WebIf compression or expansion of gas takes place under constant temperature conditions - the process is said to be isothermal. The isothermal process can be expressed with the Ideal Gas Law as. p / ρ = constant (1) where. p = absolute pressure (Pa, N/m2) ρ = density (kg/m3) The isothermal process can also be expressed as. pV = constant (1a) or.
