WebFirst law of thermodynamics is thus conventionally stated as: “The change in internal energy of a closed system is equal to the energy added to it in the form of heat (Q) plus the work (W) done on the system by the surroundings.”. Mathematically, this can be put as. ∆E _ {internal} internal = Q + W. WebA way of expressing the first law of thermodynamics is that any change in the internal energy (∆E) of a system is given by the sum of the heat (q) that flows across its boundaries and the work (w) done on the system by the surroundings: \Delta \text {E} = \text {q} + \text {w} ΔE = q+w.
