Question

limitations of the first law of thermodynamics​

Answer 1

Explanation:

The limitation of the first law of thermodynamics is that it does not say anything about the direction of flow of heat. It does not say anything whether the process is a spontaneous process or not. The reverse process is not possible. In actual practice, the heat doesn't convert completely into work.

Explanation:

What violates the first law of thermodynamics?

Perpetual Motion Machines

A device that violates the First law of thermodynamics (by creating energy) is called a Perpetual Motion Machine of the first kind. ... The first device supplies continuously energy with out receiving it. So this is a system creating energy and therefore violating the first law.
