In general "The Watchtowers" are the home of the 4 main Elements - Water, Fire, Earth and Wind. They're the 4 cardinal points of a compass - East, South, West and North. The Watchtower of the East is the home of the element Air and the Watchtower of the West is the home of the element Water. This is regardless in what hemisphere we live in. The Watchtower of the South is the home of the element Fire and the Watchtower of the North is the home of the element Earth. But this is only for the people

Taylor Small 09-23-13 Lab Report: Determination of Alcohol Content Blame it on the Alcohol Objective: Boiling is a process familiar to anyone who has cooked pasta or brewed tea. As heat is applied to a pan of water, the temperature of the water increases until it reaches 100°C (212°F). At this temperature, additional heat causes the water to bubble vigorously as the liquid water is converted into gaseous water, or steam. Most organic liquids will behave in a similar fashion. On heating,

Introduction: Porcellio scaber or commonly known as ‘slater’, belong to the biological group Phylum; Arthopada and Class; Crustacea. Animals that are associated with this group include; most Crustacea, shrimp, crabs and lobsters. Slaters have become terrestrial, although this may differ in physical appearance. As they have recognisable dark grey flattened bodies, being about 17mm in size and have a rough exoskeleton. They also have a pair of prominent antennas and seven pairs of legs. Slaters

The Determination of Boiling Points and Melting Points of Organic Compounds During this laboratory session, we will practice determining the boiling point of a liquid organic compound and the melting point (or we could call it the freezing point) of a solid organic compound. 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

EXPERIMENT 3 GROUP B AIM: To find the overall efficiency of plate column operating under total reflux, for a binary system (iso-propanol & n- propanol). APPARATUS: * Distillation Column with reboiler * Automatic digital refractometer * Two fluids with different volatilities. PROCEDURE: * Distillation column was filled with the two fluids. * Then we switched on the heater and set the temperature to 126.6 ̊C * And then we allow the system to reach the equilibrium.

Simple and Fractional Distillation I. Introduction Distillation is one of the oldest and still most common methods for both the purification and the identification of organic liquids. It is a physical process used to separate chemicals from a mixture by the difference in how easily they vaporize. As the mixture is heated, the temperature rises until it reaches the temperature of the lowest boiling substance in the mixture, while the other components of the mixture remain in their original

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
