Abstract
In mechanics, energy is defined as the capacity to do work, but in thermodynamics the energy E of a system is defined more generally as an extensive property (section 1.2) of the system, representing its capacity to change the state of its environment by interactions at the boundary. Being a property, energy is a function only of the state of the system. Normally, in thermodynamics, only changes in energy (that is ∆E) are considered.
