The SI unit of heat is the
AWatt (W) of power
BNewton (N) of force
CJoule (J)
DPascal (Pa) of pressure
Answer & Solution
Correct answer: C. Joule (J)
1. Heat is a form of energy.
2. Energy in SI is measured in joules.
3. Newton is the unit of force, watt of power, pascal of pressure.
4. So the SI unit of heat is the joule.
