Candle Extense Investigation

- Results: When a lighted match was held 2cm away from the unlighted candle in its smoke, the flame would jump from the match to the wick having been carried by the smoke.

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?

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.

The experiment is repeated twice and an average is obtained. This ensures the consistency of the measurement as the reading is triplicated, thus reducing anomalies. It can be seen that the reading obtained were around the same value. This proves that the results are reliable.

To conduct this experiment, a candle was placed upright in a pan of water, was lit, and the flame was allowed to fully develop. Then a graduated cylinder was placed upside down to represent an airtight chamber, and the water rose. The point where it rose to was

Millhouse Candles has an article on their website with a timeline of candle history. “A Short History of Candles” outlines this history from 3000 BC to present. This outline is broken up into four periods, 3000 to 1 BC, 1 BC to 1500 AD, 1500 AD to 1799 AD, and 1800 AD to present. Each of these time periods contain facts about the cultures that were making candles, the materials used for the candles within the periods and a technological advancement for that time.

The air pressure fell below the vapor pressure, and the water boiled. 10) Use your observations to compare the atmospheric pressure outside the beaker to the air pressure inside the beaker before lighting the candle. The pressure is equal before lighting the candle because the beaker took the air from outside the beaker, and nothing has been done to change the

The flame immediately reignited on the wick of the candle in the smoke. 5. The flame did not burn or ignite the candle wax on its own, but it caused it to remelt. 6. The flame went out after the aluminum foil was placed over it.

Trial 1: A dish was filled with approximately 2 cm water and a candle mounted on clay was place in it. The candle was lit and a jar was placed over top of the candle so that it was resting on the dish. When the flame went out the water level inside the jar was measured. This process was repeated three times.

Hypothesis If the size of the beaker was increased, then the duration time of the flame would increase as well. (not yet) Since there would be more volume in the beaker, the amount of air (and subsequently the amount of oxygen) would also be increased,

For this experiment it takes about two and a half hours to complete. Do this experiment in an open space where nothing could catch on fire as the experiment is being done. Make sure you are watching this experiment at all times and also make sure there are no little ones around. Do not play with the candles just watch it, again have no things around it that will not catch on fire like maybe your hair or any long sleeves and then it should be safe to enjoy this

The appearance and physical features of the candle made the quantitative data very different. When the students were observing the fact that a candle needs oxygen to burn, they needed to place a 400mL beaker over the candle. One of the possible errors could be the beaker was wet or it was placed too fast over the candle and this made the flame to go out. When this process was repeated the candle flame lasted longer, this could have also

In the future, this experiment could improved or expanded. One area of improvement could be to do this experiment several times and then averaged together or compare the results. This leaves less room for error and could make the data more accurate and precise.

Candles can be made out of wax or something called tallow. Tallow is a hard fatty substance made from rendered animal fat. Tallow consist of a chemical combo of fatty acids with glycerin. A little borax added or phosphorus is sometimes added to make the ash fusible. Different types of candle wax burns at different temperatures. The harder the wax the longer the burn-time. The color of the candles makes little to no difference in how fast a candle burns (colored candles burn faster).

I still had two more matches in the box. Dad put his lips near the candle and gently breathed on it. That somehow lit the candle. That was so cool. I tried it, but nothing happened.
