Question
Well, I'm going to grade 9, but this isn't for school. My friend asked me, and I didn't know, and this is the only place I could think of that might have the answer, google didn't do much for me.
Hydrogen and oxygen make water, right? Well, aren't they gases? How does that come into liquid form? Why is water clear, if it's a substance?
Water is only formed when a spark is applied to oxygen and hydrogen. It doesn't happen without the extra energy. When the water is initially formed, it is also in the gaseous state. If you do it at low pressure or in very small quantities, no liquid water is formed, it stays as a gas. If you see liquid water, it was done in room atmosphere or in large amounts.
As to your second question, all liquid substances are clear in their pure state or they aren't liquids. Did you mean colorless? Again, most liquids are also colorless (or every so slightly yellow), like water.
