I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.
I had a similar conversation with my wife a few weeks ago. We were watching the hydraulic press channel, where they were compressing water to very high pressures. When the water inevitably squirted out of the chamber, it turned to steam. My wife said yeah that makes sense, applying that much energy to compress the water would increase its temperature, so it wants to expand to become steam. Then I thought about it a while, and said wait, according to first principles of thermodynamics, shouldn’t compressing water lower it’s temperature?! The turns out the real world is correct, I was wrong.
You’re mixing cause and effect.
The effect of lowering temperature is shrinking gases. If you force a gas to shrink it will increase temperature.
