Water Molecule
States of WaterWe recognize that water isn"t always "wet", periodically it"s frozen into ice or snow. Depending on the temperature and energy that the molecule in water, water can exist in 3 states:Ice - ice is the solid kind of water. When water gets listed below 0 levels C (32 deg F) it will freeze and also become ice.Liquid - This is the wet stuff us drink and swim roughly in.Vapor - once water evaporates or gets above 100 degrees C and also starts boiling, water turns right into its gas state dubbed vapor.

Water ~ above EarthWater is literally everywhere the Earth. Approximately 70% that the Earth"s surface is spanned in water. Approximately 97% the the Earth"s water is in the oceans. This water is salt water and we can"t drink it. An additional 2.4% the the Earth"s water is frozen water in glaciers and the polar ice cream caps. This leaves around 0.6% the the water as freshwater in rivers and lakes the we can drink.
Does water have actually taste?Pure water actually has no taste in ~ all.

Water ice have the right to be discovered on the Moon, Mars, in Saturn"s rings, Pluto, and on Comets. Water vapor is also found in the settings of other planets like Mercury, Venus, Mars, and Jupiter.Uses that WaterWe use water for much more things than just drinking. We usage it in farming to prosper food, in cleaning to to wash our clothes and dishes, in firefighting to placed out fires, and also in hydropower to produce energy through dams. These are just a few ways we use water in our lives.Fun Facts about WaterWater is regularly used together the standard in scientific measurements such together temperature and volume.Water that is an excellent for drinking is dubbed potable water.Seventy percent of a human"s body is made up of water.Water dissolves an ext types of products than any other liquid.In the unified States, the average human being will use about 80 gallons that water a day.
