The Physical properties of water: 1. Knowledge of the physical properties of water: Water is the most abundant compound on Earth ’s surface‚ covering about 70 percent of the planet. In nature‚ water exists in liquid‚ solid‚ and gaseous states. It is a dynamic equilibrium between solid and gas states at standard temperature and pressure. At room temperature it is tasteless and odourless‚ nearly colourless with a hint of blue. Many substances dissolve in water and is commonly called a universal

2013 Water Pollution: Pollutants & Solutions Imagine swimming out of a narrow cavern following a scrumptious meal‚ and you come to realize it was poisonous. You begin to drown as your life slowly fades right before your very eyes; this is not a frightening hallucination. Everyday‚ schools of fish are unaware that their meals are products of millions of tiny pieces of garbage‚ assimilated. This is one of the many consequences of water pollution‚ which is the contamination of water bodies caused

of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate the process of osmosis and diffusion in a model of a membrane system. 2. Investigate the effect of solute concentration on water potential as it relates to living plant tissue.

Water Shortage or Water Misuse The United States of America is known for her extreme overuse of everything. Americans see something they want and they simply take it. It was true when the young country pushed westward. The Native Americans were already there‚ but that mattered not; it was wanted‚ so it was taken. It is still true today. Americans as a people see what they want and they take it with very little regard to who had it first or where more might come from. Water is one of those

The importance of water Water is one of the weirdest compounds known to humans. The difference between the boiling point and freezing point of water is one of the largest ranges of any compound. It is this span of temperature that mirrors the range of where life can exist‚ from bacteria to humans. Water also has a very high specific heat‚ which means that it can absorb or lose much heat before its temperature changes. This is important in maintaining body heat in mammals. It also takes a lot of

Thesis Statement: Water pollution is bringing down the economy‚ destroys the beauty of nature‚ and causing harmful dreaded diseases and sickness in precious health of many individual. INTRODUCTION Water pollution progresses every day in our lakes‚ oceans‚ rivers‚ and other bodies of water that we see and use in many ways. Water is essential for all living things to survive‚ yet people still pollute it. It’s pretty sad to be taking a trip to the beach with your family and you get there to see

Hardness of Water by EDTA Titration Introduction Water hardness is caused by natural minerals that are dissolved into the water‚ predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water is “boiler

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 oxygen atom has a partial
