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.
