([View Highlight](https://read.readwise.io/read/01jqj9cx2k23xzygjdwraz6ath)) - Heat does not move from hot things to cold things due to an absolute law: it only does so with a large degree of probability. The reason for this is that it is statistically more probable that a quickly moving atom of the hot substance collides with a cold one and leaves it a little of its energy, rather than vice versa. Energy is conserved in the collisions, but tends to get distributed in more or less equal parts when there are many collisions. In this way the temperature of objects in contact with each other tends to equalize. It is not impossible for a hot body to become hotter through contact with a colder one: it is just extremely improbable. ([View Highlight](https://read.readwise.io/read/01jqj9ek67wfx3rhsq5vj2mshf))
