Question

Heat is a kind of fluid that flows from a hot object to a cold object.

• A. True
• B. False

Answer 1

The correct option is A True

1. With the increase in the temperature of a body, the vibrations of molecules or atoms increase. These vibrations are then transferred from one part of the body to another.
2. The measure of energy with which the molecules vibrate in a system is termed as heat stored in that object.
3. As per definition of heat, it is defined as the flow of energy from a warm to a cooler object.
4. The direction of flow of the heat energy takes from the substance of higher temperature to the substance of lower temperature.
5. This is because the molecules are vibrating faster and transfer their energy to the molecules vibrating slower.
6. The vibrational energy is also termed as its heat content. The heat content in the body makes it hot or cold. The greater the heat content, the hotter will be the body.

Hence, the given statement is true.
