  • It is also known as<em> "law of conservation of energy"</em>

<u>Limitations of First law</u>

  1. It doesn't provide a clear idea about the direction of transfer of heat.
  2. It doesn't provide the information that how much heat energy converted inti work.
  3. Its not given any practical applications.

<u>II law of thermodynamics:</u>

It states that <em>"the total entropy of the system can never decrease over time"</em>

It is strongly proved by two laws, they are

<em>1. Kelvin-plank statement:</em>

      He stated that "any engine does not give 100% efficiency". It violates the Perpetual motion of machine II kind<em>(PMM-II).</em>

<em>2. Classius statement: </em>

<em>    </em><em>    It states that "Heat always flows from high temperature body to low temperature body, without aid of external energy". </em>

<em>          Also it stated that " Heat can also be transferred from low temperature body to high temperature body, by the aid of an external energy".</em>
