Usually, when solids form, atoms get closer together to form something denser. This is why most solids sink in water. But solid water, or ice, is actually less dense. This is unusual. The water molecules form rings when water freezes. All that space makes ice less dense. This is why it floats. This is great […]
Why do we need to drink water?
Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation. The amount of drinking water required to maintain good health varies, and depends on physical activity level, health-related issues, and environmental conditions.
We experience water in all three states: solid ice, liquid water, and gas water vapor. That’s actually pretty unusual. While all substances can be solid, liquid, or gas, a lot of them only change states at extreme temperatures. You probably don’t see liquid silver or solid oxygen very much because their melting points and freezing […]
