Explanation:
Q: What is the unit of Heat?
✅ Correct Answer:
➡️ Joule (J)
One joule is the amount of energy used when a force of one newton moves an object one meter in the direction of the force.
📘 Explanation for Exams:
- ✅ Joule is the SI unit of heat, energy, and work.
- ✅ Heat is a form of energy, so its SI unit is the Joule (J).
- ✅ In some contexts, especially older ones or in food energy:
- Calorie (cal) is also used.
- 1 calorie = 4.184 joules
