Question

Which of the following is correct?
Heat is _ _ _ _ _ _ _.
A. moving energy
B. unmoving energy.

Answer 1

Hint: Heat energy is the energy that is exchanged between bodies that are at different temperatures. The heat energy flows from a body that is at higher temperature to a body that is at a lower temperature.

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.
From the above example, we get to know that heat is an exchange of energy between bodies. That means that heat energy flows from one body to another. Hence, heat is moving energy.

So, the correct answer is “Option 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.
