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 […]
Just 3.5 percent of Earth’s water is fresh—that is, with few salts in it. You can find Earth’s freshwater in our lakes, rivers, and streams, but don’t forget groundwater and glaciers. Over 68 percent of Earth’s freshwater is locked up in ice and glaciers. And another 30 percent is in groundwater. Lorem ipsum dolor sit […]
Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed maximus mollis malesuada.

Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed maximus mollis malesuada. Sed suscipit, tortor nec […]

Cucumbers are 95 percent water, according to Ware. This makes cucumbers a great way to stay hydrated, especially during the summer. A cup of cucumber slices is „nearly as thirst-quenching as a glass of water,” according to Eating Well magazine. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed maximus mollis malesuada.

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 […]
