Question

The gas cylinder we use at home has LPG in the form of a liquid. However, when you switch on a stove it first converts to gas which burns. What form of change is this? Explain with reason.​

Answer 1

Explanation:

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 gas burns in air it is a chemical change.
