Water has polarity. Polarity is the uneven distribution of charge. Water has cohesion‚ adhesion‚ and heat capacity. Cohesion is the attraction between molecules of the same substances. Adhesion is the force of attraction between molecules of a different substances. Heat capacity is the amount of heat it takes to raise temperature of a substance. The experiment displayed shows water can have adhesion and cohesion. The hypothesis of this experiment is if a nonpolar substance is added to water

Water is the most important substance in our evolution and our daily lives. Without water‚ life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earth ’s thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive

The Uses of water in Living Things Topics I have chosen to cover: - Osmosis & Water potential - Condensation & Hydrolysis Reactions - Digestion – the importance of water - Blood and tissue fluid To emphasise the sheer importance of water in living things and to put the content of this essay in to perspective‚ I am firstly going to inform you that the human body is approximately 50-75% water. Without water our body would be unable to successfully perform the numerous complex reactions and

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower. Materials 1 Pot A Sink A Stove 1 tablespoon of sugar 1

Latent Heat of Vaporization of Water The Latent Heat of Vaporization of Water Aim: The aim is to determine the latent heat of vaporization of water by doing an experiment of boiling water. Theory: The latent heat of vaporization is the amount of energy that is required to transfer a kg of liquid from the liquid state to the gaseous state. This transformation appears‚ when water is heated. The temperature of the water keeps increasing‚ until it has

Conserving Water Water is the most important part in each of our bodies. Our body is made up of 70% of water. Without water it would be hard to survive in this society. As important water is‚ there has been a shortage of water lately. For instance‚ we sometimes take water for granted and waste water by taking long showers‚ leaving the sink on and etc. Water has been a major issue in today’s society. There are families in this world who struggle from not having water. By conserving water‚ this will

Overview of water resources in Pakistan The total land area of Pakistan is approximately 310‚322 square miles or 88 million hectares of land‚ of which approximately 20 million heaters are used for agriculture purposes. The river system of Indus and its tributaries provides Pakistan some of the most fertile land in the Indian subcontinent. Under the Indus Water Basin Treaty of 1960 three eastern rivers namely: Sutlej‚ Beas and Ravi were allocated to India for its exclusive use. The Treaty gives

Why Sea Water is Salty The “salt” in sea water‚ and some lakes that have no water outlet such as the Great Salt Lake and the Dead Sea‚ comes from ions of dissolved minerals‚ mainly chloride and sodium which make up about 90% of salt ions in sea water. There are three main ways that dissolved minerals enter the ocean: The water cycle‚ underwater geysers know as Hydrothermal Vents‚ and underwater volcanos. During the water cycle‚ water is evaporated from bodies of water by the heat of the

importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water as a

Water: An Overlooked Essential Nutrient | Presented by: Your Name | Today I am discussing the importance of water to encourage this office to provide water as the main beverage choice in this office. Water maintains body temperature‚ maintains blood volume‚ blood pressure and supports all cell functions. (Cherif‚ et al.‚ 2010)Water is a valuable resource even in an office environment. You may not realize that an air-conditioned office is a very dry environment and will deplete your body of
