Worked Solution

Step 1: Striking the match involves motion (Kinetic energy). Step [2-9]: The friction generates heat to ignite the chemicals (Chemical potential energy). Step [2-9]: The burning match produces Light and Heat energy.

Correct answer: Kinetic energy → Chemical potential energy → Light energy + Heat energy
