Question

What is the SI unit of mechanical equivalent of heat?

Answer 1

1. The mechanical equivalent of heat is defined as that in every situation, a given amount of work would generate the same amount of heat, this implies that heat and motion are mutually interchangeable.
2. The formula to calculate the mechanical equivalent of heat :
   $J=\frac{W}{Q}$
   Here, $W$ = The amount of work required to generate heat, $Q$ = heat
3. Joule/ Calorie is the SI unit of the mechanical equivalent of heat.
