1. The conversion of LPG to gas is a physical process.
2. Burning of a gas is a chemical process (oxidation).
Burning of LPG is a chemical change because it involves a chemical reaction between the LPG (composed of hydrocarbons) and oxygen in the air to produce heat, light, and new substances like carbon dioxide and water vapor. The original LPG molecules are transformed into different molecules during the combustion process.
It releases heat, therefore it is an exothermic reaction.
When LPG (liquefied petroleum gas) is burnt, it undergoes combustion, which is a chemical reaction between the hydrocarbons in LPG (such as propane and butane) and oxygen from the air. The products of the combustion reaction are carbon dioxide, water, and heat energy. The chemical reaction equation for the combustion of propane can be represented as: C3H8 + 5O2 -> 3CO2 + 4H2O + heat.
When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.

Physical and chemical properties of LPG
LPG stands for Liquified Petroleum Gas, but is almost always construed as meaning Liquified Propane gas. Propane is an alkane with the chemical formula C3H8.
Some versions of the Mazda Axela come with a factory fitted LPG. Most of these models are available in Korea and Japan where the LPG conversion is required by law.
Liquid propane gas
LPG is produced during the petrol chemical distilling process of crude oil.Liquefied Petroleum Gas.
Energy is produced from an LPG stove by burning liquefied petroleum gas (LPG) which releases heat energy. This heat energy is used to cook food or heat a space.
The process of LPG turning from liquid to gas is a physical change, not a chemical change. It involves a change in state, from liquid to gas, without any alteration in the chemical composition of the LPG molecules.
Natural gas, gasoline, fuel oil, coal, and LPG burning are all chemical reactions ( chemical changes ). The reactants ( fuel and oxygen ) react yielding primarily CO2 and H2O., which are different chemical species than the reactants.
