Question

explain the 1st law with its symbolic evaluation ​

Answer 1

Answer:

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.

The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.

Answer 2

Answer:

☑The first law of thermodynamics states that the total energy of a system remains constant, even if it is converted from one form to another.

☑It states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
