Does 80 Degree Celsius Water Reduce In Temperature
Introduction
In this experiment, we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes, using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil, plastic wrap, newspaper, felt, and bubble wrap.
Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss, but Aluminium foil is also useful for protecting objects from gaining unwanted heat.
Plastic wrap insulates the heat but makes it that it is too hot to touch. Plastic wrap is reflective which should make it a good insulator, however the plastic is too thin and lets heat escape. the reason …show more content…
for this is because plastic wrap is made of Polyvinylidene Chloride which is known to be extremely reflective.
A newspaper can insulate heat but not that well. What that means is that it has a few insulating properties because of the air cells trapped in the wood cell fibre. The thicker the paper used the better. Felt can insulate heat because it has air pockets that trap the heat. Being surrounded by the heat that is trapped by the air pockets helps insulate it better. Finally, bubble wrap is used to keep things safe and cover fragile items to stop them from breaking but can be a great heat insulator because of the air bubbles. If kept on the flat side on the outside of the conical flask then the air pockets keep the heat in them.
By using these five different materials we will figure out the best insulator used for liquid ( in this case water).
Research Question:
To investigate which of the five materials will insulate the heat the best.
Hypothesis:
If aluminum foil is used to insulate the heat then the water will be insulated the best because the heat is bounced back at the item you are insulating ( in this case water). Also aluminium foil is the most common household item that people use to keep food hot and is used on the daily basis.
If plastic wrap is used to insulate the heat than the heat will be radiated instead of insulated because of the material that it is made of which is Polyvinylidene Chloride that is highly radiative.
If the newspaper is used to insulate the heat then we will have the poorest results as a newspaper doesn’t have insulating properties in it but it can insulated a bit because of the air pockets in the wood cell fibre.
If the felt is used to insulate the heat then the heat will be insulated well but not the best because felt has air pockets in them that traps heat. The heat is also surrounded by the conical flask.
If the bubble wrap is used to insulate the heat then the heat will be insulated well but not the best because of the air pockets. If the bubble wrap had the air pockets facing the conical flask then results would be better.
Materials:
Conical flask
Glass Beaker
Tripod stand
Wire gauze mat
150ml water
Thermometer
Bunsen burner
Stop watch
1 layer of Aluminium foil
1 layer of Felt
1 layer of Gladwrap
1 layer of Bubble wrap
1 layer of Newspaper
14 cm of sticky tape for every conical flask
Procedure:
Fill the glass beaker with room temperature 150 ml of water
Put the thermometer into the beaker
Turn on the bunsen burner and put the beaker on top with the thermometer inside
Wait for the water to reach 80◦C then turn it off when it does
Carefully transfer the water from the beaker into the conical flask that’s been wrapped in your material
Place the thermometer into the conical flask
Start the time watch
Record the temperature in a results table for every minutes
Repeat using the different materials. Choose whether or not you want to cover your conical flask from the top with the material
The independent variable is the variable that changes which is the materials we are covering the conical flask.
The dependent variable is the variable you measure which is the temperature of the water which was 80 degrees in the beginning but goes down according to different materials.
The controlled variable is the variable that doesn’t change throughout the experiment which in our case will be the 150 ml of water.

materials observations Aluminium foil
The conical flask was too hot to handle
When we removed the aluminium foil the side that was on the flask was was hot which means that the heat was absorbed
Felt
The felt was cotton which is known to be hot
The felt was a bit wet and condensated but was soaked up
Glad wrap plastic
I could see the steam escaping a bit
Newspaper
The newspaper was soaking when we removed it from the conical flask
Bubble wrap
The bubble wrap was kind of good at insulating the heat but if the bubble part was on the conical flask the heat would have been insulated better.
In this first graph it shows the beginning temperatures for all five materials and the ending temperatures.my ending result was averaged out with another group's result . There is a pattern that shows that the best results might have began terribly but it ended really well.For the glad wrap it starts of as 74 degrees celsius, the best of all materials yet ending with the worst results at 51 degrees celsius. For the Aluminium foil it starts of as 72 degrees celsius yet ends at 54 degrees celsius being the third best result. The newspaper started off terribly and ended terribly as well, with the beginning time of 71 degrees celsius and ending with 52 degrees celsius making in the second worst material. The bubble wrap started off with 73 degrees celsius and ended with 55 degrees celsius making it the second best. Finally the last and best material to insulate heat is felt with a beginning time of 72 degrees celsius and ending with 58 degrees celsius.
In the second paragraph it shows what was observed during the experiment. For the Aluminium foil it was observed that the conical flask was too hot to handle and that once removed the one side that was on the conical flask was also hot which means that the Aluminium foil was absorbing the heat. For the felt the side on the conical flask was not dry and a bit wet. For the Glad wrap plastic a bit of the vapour escaped the plastic wrap. For the newspaper, since it's made of paper the newspaper was a bit soaked and more wet then the felt. The bubble wrap was doing a good job of insulating, nothing was wet but if the air pockets were on the conical flask the heat is absorbed better and would have made an improvement in the result.
Analysis:
The results show that the best material to insulate heat was the felt, with the ending temperature being 58 degrees and the worst insulator being the the glad wrap plastic ending with 51 degrees.
The results did not support my hypothesis( which was the aluminium foil will insulate the heat the best) because the felt was made of cotton which is a material that is used for making clothing that should insulate heat. The gladwrap however let steam escape and was letting the heat leave from the conical flask. The explanation of this unexpected result is that felt has air pockets in them which hides the heat but at the same time helps keeps the water at its hottest temperature it can be, because it is surrounded in heat. The experiment was a fair test except for the newspaper, because when the material was getting tested time ran out so in the next lab lesson that was done it was started at the time we left the newspaper at, instead of doing the test from the very beginning. To make sure that the other materials that we tested was a fair test is that we cooled down the conical flask before moving on to the next material and making sure that the conical flasks were all at the same time in the beginning. There was no sources of error except for the part of the newspaper, and to improve our experiment we should be focused on the time and not recording temperatures and observations a bit late. To take this investigation further we use the felt which was the best insulator and test it on other liquids to see if the results would be any different, and if they are, what is affecting the
change.
Conclusion:
The best material to insulate heat is felt. This is because felt is a material made of cotton which is normally used to keep our body temperature high and that is what happened in the experiment. As well as the heat is trapped in the air pockets that is surrounding the conical flask. This data refutes the hypothesis which was that the aluminium foil would insulate the heat the best. If the jars were covered the data would be different, but as the control test was not covered then the conical flasks that were wrapped in material shouldn’t be covered as well. The outcome of this experiment was caused by the thickness of the material. In conclusion, the best material to insulate any type of heat is felt. This explains why most of the clothes that is worn in winter is made of cotton ( which is what felt is made of). To take this investigation further we could use change the liquid so it would be different every time and the material would be felt because it gave the best result to see if the results change.
