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

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

Air and water pollution affect the biotic and abiotic environment on a global scale. All pollutants affect individuals in different ways‚ but mainly affect those with asthma or underlying respiratory conditions. Transportation and energy consumption are the biggest contributors to pollution and global warming. With world population on the rise‚ carbon dioxide in the atmosphere is also climbing a steep hill. CO2‚ a primary air pollutant‚ is the most major concern amongst environmental scientists‚

Water is essential to all living things‚ be it plants for photosynthesis or animal or bodily functions. The human body requires water to cleanse and maintain the body. When we sustain a good supply of it‚ we are hydrated. The term for when we are lacking in water is dehydration. Staying hydrated and knowing the signs of dehydration are simple yet important tasks. The basic way of staying hydrated is drinking water. Doctors suggest a minimum of six to eight ounce glasses per day. However‚ those
