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.

When lpg comes out from the cylinder turns to liquid to gas.is this a chemical change?
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.
How does LPG gas burning on gas stove involve chemical and physical changes?
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.
Which physical and chemical change occur when LPG comes out of the cylinder and burns?
When LPG comes out of the cylinder, it changes from a liquid to a gas which is a physical change. When it burns, it undergoes a chemical change where it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor.
Is conversion of LPG to gas and burning gas a chemical reaction?
Yes, the conversion of LPG (liquefied petroleum gas) to gas and burning it involves chemical reactions. The combustion of gas (which consists mainly of propane and butane) with oxygen results in the release of heat, carbon dioxide, and water vapor. This process involves the breaking and formation of chemical bonds, making it a chemical reaction.
Gas weuse in the kitchen is LPG In the cylinder it exist as a liquidWhen it comes out from the cylinder it becomes agaschange-athen it burns change-bWhat type of change is change-a physical or chmical?
Change-a (LPG changing from liquid to gas) is a physical change. It does not involve any chemical reactions, as the molecules of LPG remain the same as it transitions between its liquid and gas states.

Is is a physical or chemical change when natural gas burns in a stove?
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.
What are the chemical properties of LPG?
LPG (liquefied petroleum gas) is a mixture of propane and butane. It is highly flammable and has a narrow flammability range. It can be easily compressed into a liquid for storage and transportation.
Which changes occurs when LPG comes out of the cylinder?
When LPG comes out of the cylinder, it changes from a liquid to a gas due to the decrease in pressure. This phase change causes it to expand rapidly and cool down, which is why LPG feels cold when released. The gas is then ready to be ignited and used as a fuel for various applications.
What is the chemical formula for 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.
Is burning of LPG an exothermic or endothermic reaction?
Burning of LPG is an exothermic reaction because it releases heat and energy in the form of light and heat during the combustion process.
What is chemical name of LPG?
Liquid propane gas
How is LPG produced?
LPG is produced during the petrol chemical distilling process of crude oil.Liquefied Petroleum Gas.
