INTRODUCTIONWater is the most essential thing for life. We need it for drinking, sanitation( wash clothes and hands) we also need it to grow food. Without water animals and people would die of thirst.Properties of water70% of planet earth is covered in water and 65% of our bodies are filled with water, it is very difficult to not be aware of how important water is in our lives. There 3 different structures of water, the first one being a solid(ice), liquid(water) and as a gas(steam). Countless people are unaware of the unique properties of water, such as Boiling Point and Freezing PointSurface Tension, Heat of Vaporization, and Vapor PressureViscosity and CohesionSolid StateLiquid StateGas StateChemistry of WaterWaters chemical formula is H2O. Water is made up of 2 Hydrogen atoms and 1 oxygen atom. This is why water is sometimes referred to as H2O. Water is called the Blue Planet because 71% of the earth’s surface is covered with water. Water exists below the earth’s surface and also as water vapor in the air. Water is a limited source. impacts that global warming and the increase in CO2 have on the hydrosphere and the biosphereRising in Sea LevelRising sea levels are a new challenge that will worldwide effect many people and ecosystems. The IPCC has said that the growth is due to the increase of temperatures and the melting of mountain glaciers and ice caps. Majority of earth’s ice glaciers are in retreat because of Global Climate Change. Many scientific research studies have shown that the melting is increasing. Decrease in Arctic Sea Ice The Arctic Sea Ice has experienced a horrific downturn in the past few decades. The polar bear populations are dropping because of the thinning of the sea ice. They are being pushed further away from land this forces them to swim longer distances most of them drown along the way. This loss also impacts the albedo, or the reflectivity of the earth’s surface. With fewer white areas of ice on the surface, the darkened oceans are attracting more heat.Melting PermafrostBecause of the rising of temperatures the Permafrost of the Tundra is melting. This will have an impact on the people that are staying in this environment that most, houses will start to sink( they will become unstable).Not only will there be an immediate effect but scientist fear that the melting Permafrost will release huge loads of carbon dioxide (CO2) and Methane (CH4), the extra greenhouse gases would further fuel global warming by capturing heat in the atmosphere.Solutions to the Increase of CO2Eat less red Purchase “Green Electricity”Make your home and household energy efficientBuy energy and water efficient appliancesWalk, Cycle or take public transport Recycle, reuse and avoid useless purchasesBuy local produceOffset what you can’t saveThe density of ice is The Density of ice: The density of ice is 0.9167g/cm3. Ice is water in a solid. Why is ice able to float in water: Ice is less dense than water, this is why ice is able to float in water. If ice was to be more dense than water then it would sink in water. This would also mean that icebergs would sink in water too since they are made out of ice.Fun Facts About WaterWater is the only natural substance found in all three common states of matter, (liquid, Solid and Gas or vapor)Water is the only common substance that is less dense in liquid form that in solid form.Water can dissolve more than any other liquid.Majority of earth’s surface water is forever frozen or salty.
