Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Present State of Indian Cricket team The Indian cricket team is the national cricket team of India. Governed by the Board of Control for Cricket in India (BCCI)‚ it is a full member of the International Cricket Council (ICC) with Test and One Day International (ODI) status. Although cricket was introduced to India by European merchant sailors in the 18th century‚ and the first cricket club in India was established in Calcutta in 1792‚ India’s national cricket team did not play its first Test match

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted

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

as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete. When the water freezes in the concrete‚ the pressure of frozen water increases

diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If

How Important is Water?As we all know‚ water is essential for mankind ’s survival. However‚ people seem to believe that our water supply is endless since there is more water than land on this Earth. Water regenerates and is redistributed through evaporation‚ making it seem endlessly renewable. So why worry?Actually‚ only one percent of the world ’s water has the capability of being used by us. About ninety-seven percent is salty seawater‚ and two percent is frozen in glaciers and polar ice caps.
