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.

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 until 25 June 1932 at Lord’s.[2] They became the sixth team to be granted Test cricket status.[3] In its first fifty years of international cricket‚ India was one of the weakest teams in international cricket‚ winning only 35 of the 196 Test matches it played during the period.[4]

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

What patterns do you observe based on the information in Table 1? There is more of a fish population in areas where there is more dissolved oxygen. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If there’s more dissolved oxygen then there will

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
