Kinetic

Temperature is mean kinetic energy, not energy over volume; compression heats a gas by doing work on it; and a gas that expands without doing work does not cool.

As an atom approaches the barycenter of a forming star, it trades potential for kinetic energy: the stuff of heat.

Good conductors of heat are usually good conductors of electricity, but that puts the causal relation backwards. Conduction-band electrons can't help but transport kinetic energy, which--randomized--is heat. Putting heat before electricity is reasonable only because of the rarity of materials like diamond that conduct heat via the quasi-particles called phonons, which are communicable crystal-lattice vibrations.

Scott Weaver's "Rolling through the Bay" is a kinetic sculpture made from more than 100,000 toothpicks, over a period of 35 years.
