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

Water ice deserve to be discovered on the Moon, Mars, in Saturn"s rings, Pluto, and also on Comets. Water vapor is also found in the settings of other planets prefer Mercury, Venus, Mars, and Jupiter.Uses the WaterWe usage water for an ext things than just drinking. We usage it in agriculture to grow food, in cleaning to wash our clothes and dishes, in firefighting to placed out fires, and also in hydropower to produce energy v dams. This are just a couple of ways we use water in ours lives.Fun Facts around WaterWater is regularly used together the traditional in scientific measurements such as temperature and volume.Water that is good for drinking is referred to as potable water.Seventy percent of a human"s body is made up of water.Water dissolves an ext types of materials than any kind of other liquid.In the united States, the average human being will use approximately 80 gallons of water a day.
