LPG is stored in a cylinder as a liquid when you burn it in the store it is in the gaseous form what kind of change occur during the use of LPG

It changes from liquid to gaseous state.
KrutiR:
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.Similarly ,burning of candle is a physical as well as a chemical change because solid wax changes to liquid form and its form can be regained hence it is a physical change but burning of wax is a chemical change.

there you go -
LPG is stored in liquid form at higher pressure inside the cylinder. Once the pressure is reduced at the regulator, liquid LPG is converted in to gaseous LPG and flows to burner slightly at higher pressure than atmospheric.. Only change is the reduction in liquid LPG pressure and become gas at outside temperature…

is it a physical change or a chemical change
thanks
this is my worksheet question so how I write this answer
ok
