    decided to candles containing dyes because the are most common. (Figure 1) Wax Different candles use different types of waxes in their candles. I found out that the most common candle wax used it paraffin which is a product of petroleum refining. Beeswax is also used in some countries but is very rare though it does have a growing overseas demand it still isn’t available in most countries. Beeswax however is a better option for candles as it is better for the environment. In this project I will be using paraffin candles as they are most common. Wick wicks/oxygen The wick is the cord or string that we light and use it to hold the flame. 99.9% of the time wicks are made with braided or rolled cotton. Once in a blue will their be something else used other than cotton. The size of the wick does affect the burn rate so I will use the same size (length and width) wick in my experiment. Through out research i found out that oxygen also affects the burn rate of candles. Too much oxygen can lead to more combustion. I have decided to keep both of the candles in a room with no open windows so both the candles get the same amount of oxygen. Testing Procedure Experimental Research: Do white Candles burn faster than coloured? Aim: To find out if dye can affect the burning speed of paraffin candles? Testing Procedures: Place two 5 cm candles ,one white and one blue, onto two foam blocks at the same height and in the same room. Mark 1 inch down each candle Burn both of the candles…

  • Separation Of Glucose Synthesis Essay

    partner should prepare a test tube that contains 10 mL of the lactose solution. Make sure to label the tube as being Tube One. Another lab partner should prepare a test tube with 10 mL of the lactose solution and 1 mL of the lactase solution. Take caution in measuring the solutions. Label the tube with lactase and lactose as being Tube Two and cut off an appropriate amount of paraffin wax paper to cover the opening of the tube. Press the paper tightly to the tub and turn upside down several…

  • Synthesis Of Beeswax

    Candles are made up of chemical compounds pressed together in the form or a candle. They are made of two totally different types of wax which is Paraffin wax and Beeswax. The Paraffin candles are 95% of the world’s population of candle production. But when it comes to the beeswax the beekeepers can only used one or two pounds of the wax for every hundred pounds of honey they are able to harvest. They are also thought being able to clean the air because when the beeswax candle is burned it…

  • Density Determination Experiment

    Equal amounts of water, hexane, and ethyl alcohol were added to the test tubes and mixed thoroughly. The solubility of the sample was observed and noted. This procedure was repeated using Naphthalene and paraffin as the solutes. Density determination Mass of a beaker was measured. Then, a volume of 10mL of the unknown substance was placed into the beaker and the mass of the beaker and the sample measured. Using the obtained mass of the unknown liquid, its density was calculated. Boiling…

  • James Chadwick's Atomic Model

    particles, or a helium nucleus emitted by some radioactive substances, at beryllium metal and observed that a non-ionising radiation, believed to be gamma rays. The Joliot-Curie couple allowed the radiation to strike a block of paraffin wax, and it was noted that the wax released protons. By measuring the speeds of the protons, they had ruled out the hypothesis of gamma rays because if it was gamma rays, they would have to be very energetic to knock protons from the wax. Chadwick and Rutherford,…

  • Magic Shell Thesis

    Magic Shell has a “secret ingredient”. 1. Magic Shell’s “secret ingredient” is edible-grade paraffin wax, or a colorless soft solid. 2. Magic Shell isn’t the only food product that uses this ingredient, chocolate uses edible-grade paraffin wax for the shiny effect produced. B. Magic Shell has a special way of using this ingredient as well. 1. Magic Shell makes sure the ingredient is kept warm before using. 2. Magic Shell does this because wax melts at a warm state and hardens at a cooler…

  • Biofuels: Are They The Future?

    fuel can be defined any such chemical that reacts with oxygen to release energy, heat. As previously mentioned most of the fuels that are in used today are fossil fuels; coal, gas, oil, and combined products such as kerosene and paraffin. They were produced by plants which photosynthesized millions of years ago, mostly in the Carboniferous period. These chemicals are also important raw material for chemicals such as dyestuffs and detergents. They are finite, which one day they will run out…
