\bf {The First Law of Thermodynamics for Closed Systems}\\
... Work is energy expended when a force acts through a displacement. Boundary work occurs because the mass of the substance contained within the system boundary causes a force, the pressure times the surface area, to act on the boundary surface and make it move. This is what happens when steam, the “ga ...

Outline Introduction State Functions Energy, Heat, and Work
... Types of Work: there are many different ways that energy can be stored in a body by doing work on it: elastically by straining it; electrostatically by charging it, polarizing it in an electric field, magnetizing it in a magnetic field; chemically by changing its composition with a chemical potentia ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
