Question

Write The Limitations Of First Law Of Thermodynamics

Answer 1

Answer:

• 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.If it would have been possible to convert the whole heat into work, then we could drive ships across the ocean by extracting heat from the water of the ocean.

Answer 2

Answer:

1. The first law of thermodynamics merely indicates that in any process there is a transformation between the various forms of energy involved in the process but provides no information regarding the feasibility of such transformation.

2. First law does not provide any information regarding the direction a processes will take whether it is a spontaneous or a non spontaneous process.
