Expert Answer

Step 1

 

Joule’s constant shows the relationship between the heat produced and the kinetic energy.it is also known as the mechanical equivalent of heat.

 

Step 2

The experiment to find the joule’s constant was first conducted by British scientist James Prescott joule in which he found that expenditure of the same amount of work always produced the same amount of heat.
