Which law of thermodynamics is used to understand the concept of energy conservation ?
First law
The first law of thermodynamics states that energy can neither be created nor destroyed; it only changes from one form to another.
For a system it is written as \(\Delta U = Q - W\), where \(\Delta U\) is the change in internal energy, \(Q\) the heat supplied and \(W\) the work done by the system. This is the law of conservation of energy applied to heat and work.
The zeroth law defines thermal equilibrium and temperature, the second law deals with the direction of processes and entropy, and the third law concerns entropy approaching a minimum at absolute zero.
Hence, First law.
