Question

Maria’s father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In this case, the stored chemical energy in the logs was changed into
A) electrical energy.
B) mechanical motion.
C) heat and light energy.
D) electrical and heat energy.

Answer 1

It was changed into heat and light energy.

Answer 2

As per the question the crumpled paper was burnt .

When the paper was burnt,it produces light.One also feels the sensation of heat.

The electrical energy is due to the flow of electrons. Here no electronic motion takes place.Hence no electrical energy will be produced.

Mechanical energy is the sum total of kinetic and potential energy.The kinetic energy is the energy gained due to the motion of the body and potential energy is the energy gained due to the position or configuration of the body.

Hence from above,we can get that the correct answer to the question is-C] Heat and light energy.
