It also has a one of the biggest liquid ranges (range ≈ 30&deg; - 2,300&deg; C) and expands predictably in the temperature range of 30&deg; - 500&deg; C, which is important in making microthermometers used for high temperatures at cellular levels.
<Tab/>In conclusion, the ability for something to expand when cooled has its advantages, and is not something totally unexplainable.
