Liquefied petroleum gas (LPG) used in kitchen exists as a liquid in the cylinder. When it comes out of cylinder, it becomes a gas (process A) and then it burns (process B). Choose the correct statement.
A
Process A is a chemical change.
B
Process B is a chemical change.
C
Both processes A and B are chemical changes.
D
Both processes A and B are physical changes.
Text Solution
Verified by Experts
The correct Answer is:
B
Process A involves change of state from liquid to gas and is a physical change. Process B involves change of a gas into heat and light, which is a chemical change.
