Why Boyle’s law cannot be used to calculate the volume of gas which is changed from initial state to final state during adiabatic expansion?
Because temperature is increased in adiabatic expansion
Because temperature is decreased in adiabatic expansion
Because temperature is constant in adiabatic expansion
Nothing can be said
Boyle’s law is applicable only for the processes when the temperature is constant. In adiabatic expansion, the temperature of the gas is lowered. Thus, Boyle’s law cannot be used in this case.
Therefore, Option(2) is correct
