Question

Energy cannot be created or destroyed. It can only be transferred from one form to another. Energy that is "wasted," does not disappear. Instead, it is transferred to its surroundings and spreads out so much that it becomes difficult to do anything useful with it. Incandescent light bulbs are very inefficient in energy transfer. Energy-saving lightbulbs, such as fluorescent bulbs transfer a greater proportion of electrical energy as light energy. In fluorescent bulbs what kind of energy is "wasted" in the energy transfer from electricity to light?

A) heat energy
B) kinetic energy
C) chemical energy
D) electrical energy

Answer 1

A: heat energy

Step-by-step explanation:

because as we light up the bulb it gives us light energy

but when we touch it we feel that it is hot (heat energy)

the heat energy given of is not for our use and goes to waste

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

Heat energy is defined as the energy produced due to the movement of particles, atoms or molecules in an object.

Kinetic energy is defined as the energy acquired by the molecules of an object because of their movement due to increase in temperature. More is the increase in temperature more will be the movement of molecules.

Chemical energy is defined as the energy which is stored within the bonds of a chemical compound.

Electrical energy is defined as the energy which arises due to the flow of electrons or ions in a substance.

In fluorescent bulbs, heat energy is wasted in the energy transfer from electricity to light.

Thus, we can conclude that heat energy is wasted in the energy transfer from electricity to light.
