LPG is Liquified petrolium gas, which is a naturally occurring gas but when it is filled in cylinders it is compressed and converted into liquid due to high pressure. But when we use this, the due to release of pressure, it again converted into gas form.

LPG - propane - cannot be both a liquid and a gas at the same time.

LPG - Liquid Petroleum Gas - is stored under pressure, as a liquid, in a gas bottle.  

It turns back into gas vapour when you release some of the pressure in the gas bottle by turning on your gas appliance.

The LPG gas vapour is held in the top of the bottle and the liquid LPG at the bottom.

Burning of LPG involves both physical and chemical changes because when LPG comes out of cylinder and is converted from liquid to gaseous state it is a physical change.When the gasburns in air it is a chemicalchange.

Change A is from liquid to gas while change B is from gas to fuel. They both are not the same.
