Question

The light bulbs in an office building give off tremendous amounts of heat. Bacause heat is a form of energy, this heat could be trapped and used to offset our need for electricity, thus saving energy and money.

Answer 1

Answer:

False

Explanation:

When the light bulbs in an office building or any house is lit, it gives out light and some of of heat energy and the temperature of the room increases to some amount because of the heat produce by the light bulb. But this heat energy produce is very very negligible and so its conversion to other form of energy or the use of this heat energy to offset the need for electricity is not possible. We can store this heat energy emitted by the light bulb and is rejected to the surrounding. We cannot make any use of this energy because of its low quality.

Thus, heat energy emitted by the light bulb cannot be trapped or stored and cannot be used to offset the need for electricity.

Answer 2

The answer to this question is false.
