how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

Title : Water Crisis Introduction : - water always been a natural resource - 80 countries now facing water shortage ‚ 2 billion people lack access to clean water. - global demand for fresh water will vastly outstrip reliable supply in many parts of world. - 97.5% of water is sea water ‚ left 2.5 % of “ fresh water “ but inside include glacier ‚ ice packs ‚ soil moisture ‚ atmosphere ‚ groundwater . Factors driving to this situations : 1. Demographic pressure population growth rate

the Water Cycle The main parts of the water cycle are evaporation‚ condensation‚ and precipitation. They go together in a circle/cycle called the water cycle. None of these parts can be missing. (Well‚ everything in the water cycle is needed.) Evaporation- Evaporation is when water turns into water vapor and flows up into the sky. You can’t see it because it’s now gas and gas is invisible. Evaporation usually happens on hot‚ rainy days because the sun’s energy turns water into

THE WATER CYCLE Introduction: The water around us has been All the water around is has been here for many‚ many years. The reason is because the same water is just around a cycle. There are several steps in this cycle. In my opinion‚ this is a very interesting and fun project to do. Problem: What is the water cycle? Research: Water is vital for every living thing. When the Sun heats‚ it causes the water in the oceans‚ ponds‚ lakes and even puddles in the street to warm and evaporate

Water is life. Water is the most important thing for survival. Without water it is impossible that a planet be inhabited. Wherever we have water we find life. Our planet earth has 70% water. Ther firt ever living creature was tiny aquatic organisms. Water also is the means by which human beings survive. Water plays a very important role in religions around the world. Water signify spiritual purity being used for praying. Water also helps in agriculture.Water is the most important thing for survival

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

Water In Life on October 29‚ 2012 at 7:58 pm Water is the essence of life. There wouldn’t be life without water and that is why we are look for water on other planets. Because where there is water‚ there is life. Water in today’s world is not given that much importance. Especially by the people who can afford (in money terms) to waste water. We live in a world driven by consumerism and water has been degraded from the state of essential to life to disposable. We are experiences a massive shift in

Cause and Effects of Water Pollution Water is a key resource on our planet and is undervalued by humans causing water pollution. Water makes up 70% of the earth and 60% of the human body‚ therefore the pollution of water is in need to come to an end because it is essential to all living aspects on earth ("Causes and Effects of Water Pollution…"). Water pollution is typically caused by littering‚ industrial waste‚ oil pollution‚ and primarily‚ by the human carelessness. It needs to be taken more
