Attention Material: What comes to mind when you see candles? We associate candles with celebrations (like Christmas or birthdays) or special occasions. Candles date back to the Ancient Egyptians who are credited with making the first candles. They used torches made by soaking the spongy core of reeds in melted tallow (National Candle Association: History of Candlemaking‚ p. 1). B. Tie to the audience: I’m sure that all of us at some point have used candles for celebrations‚ romantic experiences‚ or for

Methanol(CH₃OH) is a simple compound which is also known as methyl alcohol or wood alcohol.Methanol is colourless‚flammable and most importantly very toxic.They are naturally produced from volcanic gases‚vegetation and microbes.They can also be produced in the industry by synthesizing gas.The largest and the most important use of methanol is as a feedstock in the plastic industry.They are used to make methanal and hence variety of plastics‚based on reactions with phenol‚carbamide(urea) and melamine

evaluate the environmental impact of the production of candlesticks. All the different materials and processes required to manufacture candles need to be taken into consideration to determine the impacts on the environment. The most common material used to manufacture candles is paraffin wax. Each candle comes in some type of individual packaging most of the time. Candle wicks are made using various natural fibers‚ such as reeds‚ rushes‚ or cotton. An important refinement in wick technology introduced

The mass of the candle was 59.2 grams. The measurement of the visible wick is 0.5 cm. The length of the candle is 16‚5 cm. The candle was pink in color. The circumference of the candle was 7.5 cm. The candle’s width was 2 cm. The state of the candle was solid. The candle was already used and burned. The base’s circumference was 8 cm. The candle is buoyant in water‚ The candle’s volume is 66 ml. The density of the candle is 0.897 g/ml. The candle gave off no odor. The top of the candle had a smooth texture

However‚ Methanol could prove to be the solution the human race is looking for. Methanol could be used to replace gasoline in our cars for future years to come. Methanol is easy to make because it originates from our trash and biomass. That means that we won’t have to dig or frack for Methanol like we do for oil. When it comes to efficiency‚ Methanol shockingly wins that category over gasoline which is another advantage to converting to Methanol. On the other hand‚ Methanol has

How did you figure this out? The two unknown substances were the methanol and propenol because each of them were being tested in this experiment to discover the boiling point of each of these alcohols by analysing each of their temperatures to eventually discover the averages. 3. Explain results using scientific reasoning

of combustion of paraffin (candle wax) by burning a candle and holding a calorimeter (a soda can) filled with 98.7 mL of water above the flame. The heat released by the candle was absorbed by the water in the can. It was important to place the metal chimney around the candle so that minimal amounts of heat would escape; having too much heat lost to the atmosphere would cause extra error in the calculations. The assumption made was that all heat released from the candle was absorbed by the water‚
