Candle Experiment Lab Report

As the change in mass and temperature is small for both candle wax (and paraffin in this experiment), it is clear that there is little changes when these fuels are combusting in their physical states. This means that these fuels last longer but are an unreliable source of energy as a fuel. The change in temperature being small suggests that these alkanes produce poor heat output, however that fully contradicts their high experimental and theoretical heats of combustion and percentage yields. The fact that the change in temperature was so low can be experimental side effects. One being that candle wax particularly produces the extra energy source of light possibly more so than paraffin and even the experiment 1 alcohols. Another experimental error as to why the change in temperature isn’t very large could be due to the surrounds not being a fully insulator set up (calorimetry – experiment 1

It was in one of the full moon night did the experiment take place. Not only do the soft light coming from the moon together with the bright light from the candle describe even the details of the facial expressions, they also create a great contrasting with the shadow. Joseph Wright was a well-known artist with his proficiency in painting with high contrast between the light and the dark. Wright had a lot of paintings related to scientific experiments within the 18th century, and An Experiment on a Bird in the Air Pump, which was done in 1768, is definitely one of them. At the first glance, it can be seen that the people, who are the members of the Lunar Society, are doing the air pumping experiment on a bird, which is believed to be a pet of the two little girls. Although scientific

Nevertheless the hypothesis was accepted, there were many errors that could potentially affect the lab results. A practical error within the lab is that the water that was used to conduct an incomplete or complete combustion was comprised of other minerals.The water that was used within this lab originated from the tap. The water that came from the tap has previously treated with high amount of chemicals to ensure that microorganisms and bacteria are non existent within the water. The contaminants that exist within the taps are toxic metal salts, pesticides and hormones, while it may also be contaminated with microbes or chemicals that exist within the pipes of the tap. There can be a potential of lead, protozoa, and bacteria and/or possibility be comprised of other microbes and chemicals existing within the pipes.(Geoff, 2018) With the exposure of the flame, the contaminated within the pipes could of been highly reactive to heat which consequently could of most likely affected amount of soot created, producing

The white candles burn faster than blue candles, in our experiment we took two colors of candles white and blue, then burned them until there was no wax left. It took four trials to try and do this experiment and to get a good amount of results to compare. The white candle in all three trials burned faster than the blue one. In our hypothesis we thought that the blue candle would burn faster because the chemicals put into the candle to make the color would burn fatser. What actually happened was the white candle burned faster. I thought the white candle would burn slower because they are used for emergency candles when say the power goes out, well that's what people said ,but that's not what happened. So the white candle burned fastest and

Inspired by the rustic and California style, this Home California Romantic Single Wick Candle by Ralph Lauren is an elegant way to fragrance your well-appointed interior. It unfolds the comforting aroma of cashmere wood, incense, elemi and smooth vanilla, poured in a gold-tone glass vessel. A wonderful gift idea for the festive season, this candle is made with natural soy wax and a lead-free candle wick to give an even burn for up to 120 hours.

One of the experiment is comparing the weight of a balloon filled with air to a deflated balloon. By hanging both on a hanger that is balanced on a pencil, you see the balloon filled with air weights a little bit more than the other balloon. Another experiment is filling an empty grocery bag with air and tying it shut. This experiment allows you to feel the air and maneuver it, not see it.

You might be thinking why do we do experiments in science? Why not simply learn things and move on? But in true, science is all about experiments and in middle school we do lots and lots of experiments. For example, one experiment we performed is the pink string activity. In that experiment you have to get a rope and wrap it around you and your partner's hands and twist the string. By using teamwork and strategy you and your partner have to untwist the strings without taking the string off your wrist. It was really exciting to problem solve to try and untwist the string. Another experiment we did was Saving Sammy where you get a small container and put a Lifesaver gummy under the container and a gummy worm at the top. By only using a paperclip

One day in 2017 The Candle was sitting in his office thinking about his genius plan. He had a plan to do what he wanted to do his entire life, to take over the world. He told his scientists to get his super suit with the extra patents that can resist radiation. He did this because he was going to release gasses and everybody who breathes it will be his servant forever. This gas can go through gas masks and as far as he knew there is nobody that could stop it. The Glacier had been looking into this plan and watching The Candle’s every move. When he realized what he was doing he started to make a plan.

The amount of uncertainty for the net heat of combustion was calculated to be ±0.3 kJ/g with the net amount being 43.3 kJ/g. The average effective heat of combustion found in candles was found from incident heat flux exposures of 10–40 kW/m2 using the cone calorimeter and was found to be insensitive to the heat flux. The amount of released heat ranged from 800 to 4150 kW/m2 (Hamins et.al, 2005). The experimental groups produced results similar to the control group. The results of the study showed that the combustion process was almost completed during the time of experimentation. It was observed during the experimentation the candle did not emit any visible soot from the flame. The mass burning rate, candle regression rate, and flame height help characterize the burning behavior of candles. During the experimentation, the candle burned for 12 to 15 minutes in order for a steady burning behavior. When the candle flame exhibited a steady burn, the the base of the flame also exhibited consistency with the top of the candle within a range of 1–2 mm. The average flame height was measured to be 42±1

So this is what keeps the air trapped when vertically held in water. The scientist then got another soda can and added water with an eye dropper. He put the can on the heater, the can instantly made the water from the eye dropper evaporate into water vapor. Then the scientist again and inserted the can into the water the results, the same with the can being full of

Does the number of candles effect the height of the water? This was the question we asked for our experiment. The hypothesis was that the number of candles does effect the height of the water. If the number of candles does effect the height of the water, then as the number of candles burned increases, the height of the liquid will increase.

Fruits and vegetables may contain amounts of electricity. They contain large amounts of water, the water in them make them good producers of electricity. The more citric and ascorbic acid in the fruit and vegetable creates more conductivity leading to more voltage. A related experiment to mine is powering a lightbulb with a fruit or vegetable. Many people have tried powering a light bulb with different fruits and vegetables, but will they power an electronic device? Most people who have tried powering a small light bulb have succeed. The two different metals, copper and zinc, will probably help transfer the electricity to the device or light bulb. Powering/charging an electronic will probably need more electricity than just a light bulb.

This lab was not very fun, but it helped in learning the information. After this lab I learned how to find the heat gained/lost and I also learned how to calculate the heat of combustion of the candle and the molar heat of combustion of paraffin. Going into this lab I had no idea what these terms meant. After research, I discovered that heat of combustion is the amount of energy released in burning completely one mole of substance.

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.

Today, I will be testing the effect of candle light in a room that has no other light sources. While doing this I will observing the effect of low light on cast shadows as well as the effect of candle light on walls. In addition, I be observing the shift in the intensity of light when adding two candles and later three candles. Before this I will be describing the candle in order to make sense of some of my observation in relation to the color of the candle and how that effects the light it emits. The candle itself gives of an intense fragrance of apple cinnamon in tandem with its rich color of deep red, it is placed in a glass container that is similar in size to a 8 ounce glass. For this exercise I have chosen to place the candle on the ground in a dark corner of the hallway. The space has various objects lining the walls, and a few items on the floor as well. The color of the walls are a lemon yellow and in the darkness its color is faint and is more reminiscent of a gray. I place the candle on the ground and it creates a immediate ring of light around its self, the color of the light contains a tint of red and the effect is creating a halo around the candle. Although, surrounding the candle’s ring of light, a darker tone represents the shadow of the candle itself. This initial ring of light on the ground creates the sense of movement in the candlelight by moving in an out mimicking, a camera lens opening and closing. Looking around the room, I notice the candle light
