Expert Answer

Step 1

Perpetual motion machines are against both first and second laws of thermodynamics .

Step 2

Perpetual motion machine of first kind (PMM-1) is a cyclically operating device which produces continuous work without consuming any energy from surroundings.

According to first law of thermodynamics perpetual motion machine of first kind is impossible.

First law of thermodynamics says that energy ca...
