Candle Burning Lab

Heat the bottom of the candle and secure it to a cardboard square on your lab counter. Light the candle and allow it to burn for several minutes. Note any changes. Briefly describe the burning candle.

If the difference between the recorded times are more than 10%, add a third trial. Repeat these steps with each size beaker. Calculate the average time for each beaker and record the data. The next step of the lab exercise is determining the exact volume of the beakers used in the burn time experiment. Fill a beaker to the top with water. Carefully pour the water from the beaker into a graduated cylinder. Reading the meniscus, record the exact volume into a data sheet. Repeat this step with each size beaker until all volumes are recorded into the data sheet. The final process of the Graphing and Estimating lab is plotting the recorded data onto a graph. Using the data recorded for burn time, in seconds, place the data on the vertical axis. Use the horizontal axis for the volume in milliliters. With the data points plotted determine whether a straight line or a simple curve will best represent the data. Now, obtain a jar and determine the volume. Fill the jar to the top with water. Carefully pour the water into a graduated cylinder. Precisely record the data. Using the plotted data on the graph and the simple curve or straight line to predict how long it would take for the flame to burn out on the candle if it was covered with the jar that was just measured.

This article focuses on the Revolutionary period of Colonial Williamsburg when candles were a primary light source in homes. At this time in history there were four primary substances used in making candles, spermaceti, tallow, beeswax, and myrtle or bayberry wax. The three latter substances were produced in Virginia. Methods of making these candles and how they were shaped are described in the article.

Purpose: To make observations about a burning candle in order to use the kinetic molecular theory to explain how a candle works. Materials: Wax candle, wooden splint, drinking straw, safety goggles, candle holder, matches Method: 1. The required materials were selected and brought to the workstation.

Try to repeat the experiment to compare the weight of the candle instead of its height. Do you think there will be any difference in your findings?

1. Place a small amount of wax from a birthday candle into a test tube. Heat gently over a burner flame until the wax melts completely; then allow

Then take a wooden splint out of the beaker that it was in and insert the tip into the hottest part of the flame. Then the person that was using the spectroscope would then align the light slit in the spectroscope to the color of the flame. They would then read off what they saw on the emission line spectrum and the estimated wavelength numbers. We would then repeat the process of using the spectroscope again for another trail of the same substance. After this we would repeat the same process of the two trials for all known and unknown substances.

the lit candle, then the candle will stay lit for longer if it’s covered by the largest beaker (400 ml) ,because fire needs oxygen to stay alive.

The fun filled journey you take when you burn a Prize Candle speaks to your sense of sight, smell & touch.

element of a candle can affect how fast it burns, I wanted to see how this experiment turns out http://candles.lovetoknow.com/Do_White_Candles_Burn_Faster_than_Colored_Candles

The hypothesis that temperature will affect the length of time a glow stick will last was tested by measuring how long it takes for glow sticks to burn out at different temperatures. Temperature was the independent variable and the time for the glow sticks to burn out was the dependent variable. Five trials (glow sticks) were measured for each experimental temperature. The constant for all of the groups was the type of glow stick. The glow sticks used for this experiment were 10 cm yellow sticks made by

“Embarrassing as it is, I put water on it and it [the flames grew larger] you know and apparently you don’t do that. After reading the bottom [of the candle] it does tell you that... The thing was burning hot so I grabbed the oven mitts and walked outside and hit it with the water hose.”

This lab has taught me new things and helped me understand previous concepts I learned in more detail. From this lab, watching reactions between complete and uncomplete combustion helped me differentiate between both reactions. Prior to this lab, I had a bit of confusion between the two, however now I can picture the reactions in my head which is that complete combustion will make a noise and leave no residue while uncomplete combustion leaves lots of residue. These visual aids will help me remember and differentiate the two types of combustions and never cause confusion again. During the lab, only the test tubes full of ½ gas, 1/5 gas and 1/10 gas worked. This is due to the reason that me and my group struggled to close the test tubes quickly

In this project we examined three explanations that talk about (a) candle(s) in a jar and their investigation reasoning to why the labs they did were concluding in such a way. The first explanation resulted that the candle inside the jar took up all the oxygen molecules inside the flask which then lowers the pressure inside and the higher pressure outside the flask is what causes the water to rise up. The second explanation resulted in that the air pressure increases inside the jar because of the heat from the candle, which causes air to come out of the jar and once the candle cools down the pressure decreases and the pressure outside the jar increases which results in pushing the air in and making the water rise up. The third explanation resulted in oxygen inside the flask becoming carbon dioxide which then dissolves in water causing the air pressure to decrease under the glass and the higher pressure outside the flask pushed the water up the flask. I believe that explanation number three is right because the flame causes carbon dioxide to be created and that

At one time, scented candles were a rare luxury to be enjoyed only by the rich while the rest of us made do with the ordinary white candles during power cuts and at Christmas time. However, that has all changed, and an endless variety of fragrances are filling our homes and relaxing us. Candles are just one of these sources of wonderful smells, but they are also a very popular source, partially because of the number of different forms in which they are available but also because they look so good with their burning flame.
