Question #7762a

1 Answer

Boyle's law assumes that a gas in a starting situation (#P_1V_1#) will be changed by altering the volume and pressure (#P_2V_2#) but that it remains in the gas state.

If the gas is changing state, it is either beginning as a gas and turning into a solid or liquid. Or it could begin as a solid or liquid and turn into a gas.

Either way, you can't apply a gas law to something which is not in the gas state.
