What is the First Law of Thermodynamics ?

1.	What is the First Law of Thermodynamics ?
Answer» It is law of conservation energy. Energy can neither be created not destroyed, it may be converted from one from into another. Mathematically U = q + w, w = –p. V (work of expansion) U = q – p. V or q = U + p. V, q,w are not state function. But U is state function.

Answer»

It is law of conservation energy.

Energy can neither be created not destroyed, it may be converted from one from into another.

Mathematically U = q + w, w = –p. V (work of expansion)

U = q – p. V or q = U + p. V, q,w are not state function. But U is state function.
