First Law of Thermodynamics:
Statements:Energy can neither be created nor destroyed although it can be converted from one form to another.
or
Energy of an isolated system is constant.
Mathematical Expression
Heat observed by the system = its internal energy + work done by the system.
i.e. q = dE + w
For an infinitesimal process
dq = dE + dw
Where, q is the heat supplied to the system and w is the work done on the system.
