What is the SI unit of heat?

Options

  1. AKelvin
  2. BJoule
  3. CNewton
  4. DPascal

Correct answer

B. Joule

Step-by-step solution

Heat is a form of energy that is transferred between two or more systems or a system and its surroundings due to a difference in their temperatures. It always flows from a system of higher temperature to a system of lower temperature. Since heat is a form of energy, its SI unit is joule.
