What Are Limitations Of First Law Of Thermodynamics?

Answer:

The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy.

First Law of Thermodynamics Equation

The equation for the first law of thermodynamics is given as;

ΔU = q + W

Where,

  • ΔU = change in internal energy of the system.
  • q = algebraic sum of heat transfer between system and surroundings.
  • W = work interaction of the system with its surroundings.

Limitations Of First Law Of Thermodynamics

The law states that whenever a system undergoes any thermodynamic process it always holds a certain energy balance. However, the first law fails to give the feasibility of the process or change of state that the system undergoes.
