Chapter 14, Problem 1RQ

Which of the following are methods of heat transfer?

1. a. Convection
2. b. Conduction
3. c. Temperature
4. d. Radiation
5. e. Potential energy

To determine

Choose the correct option.

Answer to Problem 1RQ

The correct options are “a. Convection, b. Conduction, d. Radiation”.

Explanation of Solution

Convection is the moment of hot molecules of water or air from a region of hot reservoir to a region of cold reservoir.

Conduction is the flow of heat from one solid medium to another solid medium when placed in contact.

Temperature is the degree of heat present in an object. It is the amount of hotness or coldness of the body.

Radiation is the emission of heat energy in the forms of a wave. This type of heat transfer is similar to light.

Potential energy is the amount of energy required to bring a unit positive charge from infinity to that point.

Therefore, the processes by which heat is transferred are convection, conduction, and radiation. Therefore, options a, b, and d are correct.

The temperature and potential energy cannot perform heat transfer, therefore, option c and e are incorrect.

Conclusion:

Hence, the correct options are “a. Convection, b. Conduction, d. Radiation”.
