## What is meant by mechanical equivalent of heat?

In the history of science, the mechanical equivalent of heat states that motion and heat are mutually interchangeable and that in every case, a given amount of work would generate the same amount of heat , provided the work done is totally converted to heat energy.

## Is joules heating a reversible effect?

Joule ‘s law of heating is not a reversible process, because we can not directly produce electric current by just heating any resistance.
