TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation

chemical equilibrium is already achieved. A reaction is said to be at equilibrium when the following conditions exist. 1. 2. 3. Several factors such as temperature‚ concentration and pressure affects the rate of reaction which can cause an effect in the chemical equilibrium. A general rule is used to predict the direction in which an equilibrium reaction will move which is called the Le Chatelier’s Principle. It states that if an external stress is applied to a system at equilibrium‚ the system

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Sam Preusser Mr. Staude U.S. History 25 April 2013 Truman Doctrine VS. Marshall Plan The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making

Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated
