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
