The first law of thermodynamics is based on the law of conservation of energy, It states that ” Energy can neither be created nor be destroyed but can be converted into one form to another form “
Also,
It can be stated as, ” The total amount of energy in the universe remains constant, although it may undergo the transformation from one form to another.”
Advantages:
- The total energy of the universe remains constant.
- Different form of energy are interconvertible.
- when one form of energy is disappear, an equivalent amount of another energy is appears.
Limitations :
- The extent and direction of the convertibility of one form of energy into another.
- It doesnot explain why chemical reaction do not procees to completion.
- It doesnot explain why natural processes are unidirectional.
- It doesnot explain the feasibility and spontinity of process.
