Is the temperature scale directly proportional to the heat energy? I think the amount of energy needed to raise water by 1 degree is the same no matter the starting temperature for example. Is 100°K double the heat energy of 50°K?
Kelvin doesn’t have degrees btw you just say 50K or 100K because it’s an absolute temperature scale as opposed to an arbitrary or relative one like Fahrenheit or Celsius. I’d expect that the energy would be double though that’s more of a feeling.
As long as the mixture of the substance remains constant and there are no phase changes, heat energy and temperature are linear and half the heat energy is half the temperature. In reality this only works for solids because otherwise, halving the heat energy would definitely involve phase changes.
Well at some point you encounter a phase change, which complicates things, but mostly the heat capacity (how much energy it takes to raise the temperature) is fairly constant. In an ideal gas it is exactly constant, but that is a bit of an approximation, even if it works quite well for most gases.
That wish just condenses the atmosphere of half of the planet for half of the time. How do you like your puddles of liquid oxygen now?
