Comment on this statement: “There are two ways to carry out an adiabatic process. Once is to do it quickly and the other is to do it in an insulated box.”

The process in which change in pressure, volume and temperature takes place without any heat entering or leaving the system is called adiabatic change.
Consider some gas contained in an insulating box fitted with an airtight piston. On compressing the gas, heat is liberated. This liberated heat cannot move out due to the insulation of box, resulting in a rise of temperature.
Whenever change is said to take place quickly, it should be taken as an adiabatic change. The word ‘quickly’ signifies that the system hardly finds time to get the heat exchanged with the surroundings.
