Ok this is a physical one.
Temperature is just the total speed of molecule vibrations in an object.
Vibrations are movement. Movement needs energy. All things thrive to be in an energy neutral state, energy always disperses, disbalances are always balanced out.
This means that the natural state of objects is 0°K, the lowest temperature possible, no movement.
That is why you should fill up your fridge and freezer! The only energy you need is for removing heat that comes into the thing and would in turn transfer to cooler objects and warm them up.
But keeping things cool itself doesnt need any energy 🤯
And if you heat it up then less air comes in, and the incoming air will be cooled down faster (energy balanced out between low density air and high density things). So the overall temperature doesnt spike as much and less needs to be transported off.
Why would you assume the natural state of a ‘object’ is absolute zero?
Because then it doesnt move and there is no energy it can give to the surrouding. Actually there is, stored in molecular bounds. But no molecular movement, just atoms I guess
So you propose that all matter naturally has zero volume because its at absolute zero by nature.
Objects at zero Kelvin are not zero Volume?
I guess my physics books were wrong then. Nah.
