... Did you know that a match also has potential energy? It is in the form of chemical energy. This energy comes from the bonds between the atoms in molecules. Atoms bond when they share electrons or when electrons are transferred from one atom to another. Bonds with more electrons have more energy. Whe ...

THE FIRST LAW of THERMODYNAMICS: Conservation of energy
... Consider a gas expanding into an evacuated cylinder (vacuum). Since p is zero, no mechanical work is done and dw = 0. Imagine that the process is also adiabatic (perfectly insulated walls), so dq = 0. Since dq = dw = 0, du = 0. Under these conditions, its clear that the volume of the gas changed, as ...

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.
