Question

State whether the given statement is True or false.
Heat is a form of energy which produces a feeling of hotness.
A. True
B. False

Answer 1

Hint: Heat energy is the energy that is exchanged between bodies that are at different temperatures. When we touch a hotter, some heat flows from that to our body. As a result, we feel hot. When we touch a colder body, heat from our body flows into it. Hence, we feel cold.

Complete answer:
Let us first understand what is meant by heat energy.
Heat energy is the energy that is exchanged between bodies that are at different temperatures.
Consider two bodies A and B. Say body A is at higher temperature than that of body B. Everything in the universe, by nature wants to be in equilibrium. Therefore, the system of the two bodies will attain an equilibrium temperature.
This is done by exchange of energy between the two bodies and this energy is called heat energy. The hotter body i.e. A will lose energy and the colder body i.e. B will absorb this energy. Temperature of a body is directly proportional to the heat energy absorbed. Therefore, as the body A loses energy its temperature decreases and as the body B absorbs energy its temperature increases.
This way they both attain an equal temperature.
Therefore, when we touch a hotter, some heat flows from that to our body. As a result, we feel hot.
When we touch a colder body, heat from our body flows into it. Hence, we feel cold.
Therefore, we can say that heat is a form of energy which produces feelings of hotness and coldness.
This means that the given statement is true.

Hence, the correct option is A.

Note:
Do not confuse between heat and temperature. Heat produces the sensation for hotness and coldness. Temperature is that quantity which measures the hotness and coldness of a body.
