Answer 1

Question

Chapter 11, Problem 1MCQ

To determine

The SI unit for energy.

Expert Solution & Answer

Answer to Problem 1MCQ

Option (d).

Explanation of Solution

The SI unit is the International System of Units and it is most commonly accepted.

The SI unit of heat energy is Joule. Its base units are kg·m²/s². It can also be written in terms of N·m. One Joule is defined as the amount of work done to exert 1 newton of force to displace the object by 1 metre.

Conclusion:

Joule is the SI unit of energy. Thus, option (d) is correct.

Calorie is a non-SI unit of energy. Thus, option (a) is incorrect.

Kilocalorie is a non-SI unit of energy. Thus, option (b) is incorrect.

Btu is the British thermal unit to measure heat energy. Thus, option (c) is incorrect.
