TEMPERATURE as a property that can be measured meaningfully disappears when you get down to extremely small scales, because of a curious interaction between the laws of quantum mechanics and thermodynamics. Thermodynamically speaking, temperature measures the average energy of atoms or molecules. However, as the size of the region you are trying to measure shrinks, the surface area of that region becomes larger relative to the volume in which energy is distributed,
