Water as a Universal Solvent * Because of its high polarity‚ water is able to dissolve most substances. * In a solution‚ the positive hydrogen side of water is attracted to the negative parts if the compound it is dissolving while the negative oxygen is attracted to the positive parts * “Like dissolves like” – describes whether one substance will dissolve in another. Water for example can’t dissolve nonpolar substances Concentrations on Solutions * Solvent: The liquid

specific heat is one of five properties of water that is important to life. Specific heat is defined as the heat necessary to raise one gram of water by one degree Celsius. Because water’s temperature does not change dramatically when absorbing or losing heat‚ water can absorb or release exceeding amounts of heat (by breaking and forming hydrogen bonds) without affecting living organisms in the water and at the same time helping terrestrial organisms outside the water live easier. For example‚ coastal areas

One property of water that makes life possible on earth is its solid state‚ (frozen).Water is less dense as a solid than it is as a liquid‚ which enables ice to float. When its temperature falls below 4 degrees Celsius‚ the molecules slow down to a point where they are not moving fast enough in order to break the hydrogen bonds‚ therefore making the bonds more stable. The bonds then are farther apart‚ making the solid less dense. Water is one of the few molecules that has this property‚ allowing

Water Balance of Berkeley‚ California and Terre Haute‚ Indiana Johnny L. Luckett Excelsior College Abstract This paper discovers the water budget for Berkeley‚ California in comparison to Terre Haute‚ Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters‚ where the majority of rain occurs and Terre Haute‚ Indiana where the rainfall is observed as

memories occur when you recall an event that did not actually happen. Scientists have been conducting studies to determine whether false memories actually occur and how they occur. In 1995‚ Henry L. Roediger III and Kathleen McDermott constructed the now widely used Deese–Roediger–McDermott paradigm based on the procedure pioneered psychologist James Deese in 1959. They performed two experiments on 36 Rice University undergraduate students to determine whether false memories actually occur. They tested

Genetic Variation are the differences within individuals in a population. They are what make us genetically different from one another. Genetic variation occur because of mutations in our DNA and recombination. There are multiple types of mutation such as point mutations or chromosome mutations. Point mutations are the most common where only a single DNA nucleotide is affected. Within point mutations are frameshift and substitution. Frameshift mutations are when a base is either added or deleted

What are the problems occur in as manual library system? · Data duplication can be occurred by repeating the same thing over and over. · Lack of security · Lack of storage common errors. · Too much paper wastage.Paper takes up a massive amount of room in the site. If a computer system was bought the paper could all go and there would lots more free space which could be used for other purposes. · Poor Data Storage - All the data is stored in filing cabinets. Data could be misplaced due to human

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction
