Answer 1

Claim: The cotton ignites in the piston due to the transfer of thermal energy from the compressed air.

Evidence: When the piston is rapidly pushed into the cylinder, it compresses the air inside, causing the air molecules to collide and generate heat. This increase in temperature is then transferred to the small piece of cotton located at the bottom of the piston, causing it to ignite and produce a flame.

Reasoning: The transfer of thermal energy from the compressed air to the cotton occurs due to the process of conduction. The compressed air directly contacts the cotton, transferring its heat energy to the cotton through direct contact. As the temperature of the cotton increases, it reaches its ignition point and starts to burn. Therefore, the cotton ignites due to the transfer of thermal energy from the compressed air through conduction.
