>Heat is essentially kinetic energy on an atomic level How

If you are in high school, it's very incorrect because classic thermodynamics is concerned only with macroscopic descriptions energy transfer. The statement makes no sense because thermodynamics is independent of atomic theory

If you are asking because you are curious/a brainlet wandering wikipedia click this link https://en.wikipedia.org/wiki/Statistical_mechanics

I read your link and it didn't give me any insight on the OP question. Heat is energy is it not? Where is the energy stored, if not in the atomic level movement?

An einsteinian solid stores energy in 3 dimensional lattice vibrations, 'heat' is the mechanism that transfers energy between these objects. t thermodynamics pro

So when the temperature of the solid increases, the vibrations become stronger and the mean distance between atoms in the lattice increases?

Einstein model doesn't concern itself with thermal expansion IIRC, but yes, I think thermal expansion is caused by the molecules vibrating more and thus occupying a larger space on average

Heat is dissipated "energy" which is essentially the byproduct of magnetism and induction on a subatomic scale. You may be wondering "So how come when you heat a magnet up though it loses it's magnetism"? This is because the "poles" on a subatomic scale are coherent (facing the same direction) and when you heat it up they spin wildly and incoherent. When it cools some of the magnetism will be lost because the coherency is affected and dissipated from the surrounding air molecules passing over the heated magnet.
There is no heat just as there is no object at rest. Everything is in motion CONSTANTLY at a universal scale and stopping it or moving it faster will affect it's temperature because of this. Slow it down, it gets cooler, speed it up (BY INDUCTION) and you get radiant heat that dissipates because you "borrowed" it from somewhere.

Look up what a heat pump is in the HVAC world to grasp how this concept works.
