Water
is a chemical. It’s made of two gases, hydrogen and oxygen. Water acts
like a gas sometimes (when it evaporates) but we usually think of water
as a liquid
You can make hydrogen and oxygen join to form water.
Less than 1 percent of all the water on earth is available or clean enough to drink. The rest is salty or frozen.
