Solution

The correct option is B Process – B is a chemical change.

● Process A: Involves the change in the state of LPG from liquid to gas as no new substance is formed. Hence, process A is a physical process.

● Process B: Involves the burning of LPG to form new substances carbon dioxide and heat. So, process B is a chemical change.

$Burning of LPG ⟶ C O_{2} + Heat + Light$
