Have you ever wondered how much potential energy from fuel is lost in gas-powered vehicles? Surprisingly, traditional combustion engines only use about
It’s pretty much like billiards. They just bounce. Different chemicals (types of molecule) are different phases at different temperatures e.g. nitrogen is a gas at room temp, water is liquid. Stuff that’s a gas at room temp just has less bonding forces (and often mass) than liquids or solids. So they don’t take as much heat to go fast. There’s a lot of heat even at room temp, and even at -40deg. The temperature for nitrogen to sit in one place is -210C or -346F.
