An Investigation Into How the Thickness of Insulation Affects the Time a Drink Takes to Cool Down
· Aim
In this investigation I am trying to find out how the thickness of
insulation around a drink in a cup affects the time a drink takes to
cool down. I want to find out if insulation does affect the cooling
time of a drink and if so how.
I would like to produce an unbiased and fair set of results. I would
like to produce results that match my prediction and the scientific
theory behind them. I would like there to be an obvious trend in the
results and a pattern which can be easily be used to predict further
results when changing the thickness of the insulation. Preferably
there would be no anomalous figures. I aim to undertake a safe and
well-planned investigation after which I will be able to arrive at a
thorough and decisive conclusion.
I aim to do the right amount of experiments for there to be an
accurate result, not to do too many unnecessary ones. I will conduct
some preliminary experiments to decide on what measurements I will
take and also what range of thickness to use.
My overall aim is to perform a safe, well planned, precise and
conclusive investigation into how the quantity of insulation affects
the time it takes for a drink to cool down.
· Prediction
My prediction is that the more the thickness of the insulation is
increased the longer the drink will take to cool down. I also predict
that for every two layers added the temperature change will go down by
about 2oC.
I do not predict that all of my results will follow a line of best fit
exactly as that would be very hard to achieve but they will probably
have a trend. There is a possibility of getting one or two anomalous
results but I hope that my results will follow a pattern.
Here is a graph of how I expect my results to look:
Hypothesis- Water will evaporate the quickest because there isn't heavy sugars in the drinks slowingdown the evaporation process.
The Yeti Rambler has taken off where it’s more expensive and luxurious brethren, the Yeti cooler, has left off. The explosion of demand for this particular cup is due to its highly engineered design, which features 18/8 stainless steel material and a double walled vacuum insulation, which keeps a drink hot or cold twice as long as plastic cups (“Frequently asked questions”, n.d.). The cutting edge cup also features a gasket lid that locks beverages inside of the cup, allowing one to move freely without fear of spilling (“Frequently asked questions”, n.d.). Saporito (2016) narrates the Yeti Coolers story as it was started in 2005 by Ryan Seiders and his brother Roy Seiders as a way to provide premium coolers
Situation and SWOT Analysis YETI coolers are built with purpose and are designed to withstand abuse from the outdoor elements. The entire reason the founders designed YETI coolers was to aid outdoorsman in their everyday lives. From fly fishing in Belize to elk hunting in Colorado, the YETI was made to store perishables for an extended amount of time and endure the abuse of the miles traveled. YETI’s mission statement is interrelated with their founder’s needs’, “Build the cooler we’d use everyday.” The cooler is made for outdoorsmen/women, commercial fishing, hunting, and outdoor activities that can keep game, food, drinks, beer, wildly longer and colder.
Pelican products have been made for extreme conditions and are being used in defence, emergency services and expeditions in extremely remote areas. These coolers are now available to you.

Our predicted points for our data are, (13, -88.57) and (-2, -29.84). These points show the
Experimental Summary: First, my partner and I put the marshmallow and cheese puff on T-pins and used the Electronic Balance to measure the mass of each of them. Next, we put 100 mL of water in the 100 mL Graduated Cylinder and poured it into the 12 oz. soda can. We measured the temperature of the water with the thermometer. After
heat will stay in the cup and can only escape by rising to the surface
take about 30 minutes for the water to cool down 20ºC, which is why I
Sweating and Heat Loss Investigation Aim To find out whether heat is lost faster over a sweaty body compared to a dry body. Apparatus 2 Boiling tubes 47ml max 2 Measuring jug 50ml max A Beaker 250ml max 2 thermometers Paper towels A kettle to boil water A stopwatch 2 magnifying glasses (8x) 2 corks with a small hole through the centre A test tube rack Preliminary work In my preliminary work, I need to find out how much water to use, whether the tissue should be wet with hot/cold water, how often the readings should be taken, how accurate should the readings be, how many readings should be taken and what my starting temperature should be.

Also, when we put the insulation cans in warn water the water heated up the can. And lastly, in the insulated can experiments, both cooling and heating, when the cans temperature was changed it in turn changed the air temperature
Aim: To find out what type of insulation holds the most heat for a can
Methodology: A plastic cup was filled half way with crushed ice and mixed with four spoonfuls of 5 mL of sodium chloride. A thermometer was quickly placed inside the cup to take the temperature and the
Heat energy is transferred through three ways- conduction, convection and radiation. All three are able to transfer heat from one place to another based off of different principles however, are all three are connected by the physics of heat. Let’s start with heat- what exactly is heat? We can understand heat by knowing that “heat is a thermal energy that flows from the warmer areas to the cooler areas, and the thermal energy is the total of all kinetic energies within a given system.” (Soffar, 2015) Now, we can explore the means to which heat is transferred and how each of them occurs. Heat is transferred through conduction at the molecular level and in simple terms, the transfers occurs through physical contact. In conduction, “the substance
