Chapter 9, Problem 4RAT

Heat is simply another word for

(a) temperature.

(b) thermal energy.

(c) thermal energy that flows from hot to cold.

(d) All of these.

To determine

The correct option for the statement “Heat is simply another word for”.

Answer to Problem 4RAT

The correct option for the statement “Heat is simply another word for” is option (c).

Explanation of Solution

Heat is described as the thermal energy flows from one place to another due to the variation in their temperature. In nature, heat travels from the warm thing to the colder thing until they get the same temperature level and this process is termed as heat transfer.

The amount of thermal energy depends on the difference in the temperature of the substances. If two substances are in thermal contact, then thermal energy will flow from a higher temperature to the lower temperature until the equilibrium is reached. So, it can be said that heat is simply another word for the thermal energy that flows from hot to cold.

Conclusion:

Therefore, the correct option for the statement “Heat is simply another word for” is option (c).
