2013-14 Advanced Environmental Technologies 2013-14 Holly Cross Athletic Facility Decontamination Analysis Cleaning vs. Disinfecting Introduction Cleaning and disinfecting of public transportation is a matter of technique, coupled with the proper cleaning agents. To insure that cross contamination of harmful microbes does not occur, certain steps need to be followed to take cleanliness down to the microscopic level, where the cause of the problem actually originates. Current practices

ABSTARCT Determination of boiling point and melting point of the organic liquids, in practice determining the boiling point of ethyl and Isopropyl Alcohol and the melting point of benzoic acid and Urea. However, the boiling point of a liquid is the temperature at which the pressure of the vapor above a liquid equals the existing pressure. As we heat a liquid, the pressure of the vapor above the liquid slowly increases. When this pressure equals the pressure presented in the container, the

: A. Forest and all living things complement each other as forests is important in supplying the needs of life. 1. Forest will produce oxygen and absorb the carbon dioxide. a) Oxygen released by the trees in the forest is the chemical gas that are very important to human and animal life.(Chrisz,2006) b) Trees absorb carbon dioxide in the air and replaced it with clean air to remove toxic gases that facilitate human and animal respiration. 2. Supply various kind of food.

at room temperature. More helium was added to the cylinder and the volume was adjusted so that the gas pressure remained the same. Calculate the mass of helium added to the cylinder if the volume was changed from 2.50 L to 3.70 L. (Ans: 1.44 g) 2. An ideal gas in a 2.08 L container exerts a pressure of 1.00 atm at 0 °C. Determine the required change in temperature to adjust the pressure of gas to 1.65 atm after it has been transferred to a 1.50 L container. (Ans: 51.88) 3. (a) A 10.73 g sample

You and your students may be familiar with the observation that colour leaks out of beetroot when it is cooked. Many cookbooks suggest that beetroot should be cooked with their outer skins on, and with a minimum amount trimmed from the top (by the leaves) and tail (by the taproot) to reduce the release of beet colour leaking into the water. This procedure lends itself to detailed evaluation, and provides an opportunity to discuss how you would like students to write up a practical. Cutting the

Expansion Most substances expand when they are heated and contract when they are cooled. Heat causes expansion because it increases the vibrations of the atoms or molecules of a substance. The increased vibration forces the atoms or molecules further apart and the substance becomes larger, i.e. expands. When the substance cools down, it becomes smaller, i.e. contracts. Expansion and Contraction of Solids Solids expand in all directions when heated but the amount of expansion is usually
