Is a slow process always isothermal? Is a quick process always adiabatic?

An isothermal process is represented by the equation


PV = constant … (i),


where


P = pressure


V = volume.


To keep this product constant, a small change in V will only produce a small change in P and vice versa. Hence, an isothermal process is usually a slow process.


On the other hand, an adiabatic process is represented as


PV
