Today, IQ Weather’s science blog discusses the miracle of water.
Water is something we use every day. We drink it, wash things in it, bathe in it, swim in it, and all the while probably don’t think about how important it is to life on earth!
Water can exist in three different forms at the same time; gas, solid, and liquid. The point at where all three can exist is called the “triple point”. And water’s triple point temperature falls within a range that makes our planet’s temperature livable. If it did not, earth would be a very different place!
Water stores and releases heat as it changes from one form to another. When water is boiled it must absorb enough heat for the water molecules to turn to a vapor. When that vapor cools, it releases the heat that is absorbed back into the air. And when water freezes, it releases the heat that it took to keep it in liquid form. And when ice is melted, it absorbs heat to return to liquid form. In these...
