For instance: They're...both water. They are both H2O. They are clear liquids with no color. They are wet (or not wet. Whatever side of <em>that</em> viral argument you're on). They can both be used to cook or hydrate something. Both are digestible. They're the same thing but at different temperatures. They conform to the shape of their container, etc. etc. etc.
Hot water is a result of something heating up the temperature, making the atoms go fast. Cold water is...cold.
