The Physics of Death (and What Happens to Your Energy When You Die)
In a typical car, the initial starting energy is stored in a battery. The chemicals in the charged-up battery are not in their lowest free-energy state. Then once the motor starts, the energy comes from combining the fuel with oxygen, which also lowers the chemical free-energy. By atoms jiggling we just mean that they move around, with some kinetic energy. They also squash into each other as they jiggle, and that raises their potential energy.
A Changed State
That's a pretty good question, but in order to answer it we have to clarify precisely what it is physics says about the first law of thermodynamics. The first law of thermodynamics doesn't actually specify that matter can neither be created nor destroyed, but instead that the total amount of energy in a closed system cannot be created nor destroyed though it can be changed from one form to another. Mass became another form of energy that had to be included in a thorough thermodynamic treatment of a system. The first thing we have to do is determine what a "closed system" is. When we look at a physical situation and draw an imaginary circle around it, we're defining a system.
The laws of thermodynamics define fundamental physical quantities temperature, energy, and entropy that characterize thermodynamic systems. In order to avoid confusion, scientists discuss thermodynamic values in reference to a system and its surroundings. Everything that is not a part of the system constitutes its surroundings. The system and surroundings are separated by a boundary. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself.
