Dear student,
LPG is liquefied petroleum gas, which is stored in a cylinder under high pressure due to this high pressure gas turns to liquid,when it comes out of cylinder pressure reduces and it turns into gas showing physical change, when it burns producing flame i.e. combustion this shows the chemical change.
