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:
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
The advantages of adding a fully sealable lid to our cups includes minimizing the risk of spilling the cup’s contents, as well as this lid has the potential to keep liquids at their desired temperature for longer due to the absence of outside elements constantly entering the cup. One disadvantage to making this fully sealable lid is that some of YETI’s main competitors already have this option available to our customers, so YETI would not be a first mover for this niche market as we have been in the past. But since this product already exists in competitor product lines, the introduction of a fully sealable lid to YETI products is sure to help YETI become more competitive, which results in higher sales and profit. A potential threat to this new product is that YETI will almost certainly charge more for their product, even though the product already exists on the
Our predicted points for our data are, (13, -88.57) and (-2, -29.84). These points show the

The thermometer, containers, and iron ball were secured of any possible contaminants. The stopwatch was calibrated and checked to be correctly measuring the time in seconds and milliseconds, by comparison with other stopwatches. The thermometer was checked to be accurately measuring the temperature of lukewarm water, and was al...
The data which was collected in Procedure A was able to produce a relatively straight line. Even though this did have few straying points, there was a positive correlation. This lab was able to support Newton’s Law of Heating and Cooling.
Studies have shown that big changes in temperature do not affect the capability of insulation. In one experiment, materials were set to a high heat of 300 degrees Celsius. After six months in this environment, the substances were cooled to room temperature. The dielectric constant showing the level of insulation had not changed ("Teflon PTFE fluoropolymer resin" 28).
from them. The outliers in both models was not a factor in choosing the best
An investigation to determine which of the four alcohols is the most exothermic. Prediction I predict that the most heat given out per mole burned would be by Propanol because the size of the alcohol molecules might increase with heat. Alcohols produce heat when they burn oxygen or air. The amount of heat produced per mole of alcohol is proportional to the amount of air present.
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
Aim: To find out what type of insulation holds the most heat for a can
heat will stay in the cup and can only escape by rising to the surface
First of all, the purpose of this lab was to determine the water’s vapor pressure at different temperatures as well as to measure the molar heat of vaporization of water using the Clausias Clapeyron equation. The first concept out of many represented in this lab is the ideal gas law. The ideal gas law is used to get the number of moles of air trapped in the 10 mL graduated cylinder. Once we cooled the system so that water vapor is extremely minute, and then we determined the number of moles of air using the ideal gas law. The number of moles of air equals to the pressure (in atm) times volume divided by constant times temperature. One would assume that when the water is heated to 80 degrees, the number of air molecules in the air bubble would decrease, but it actually stays constant. This is due to the fact that there is no air coming in or out of the cylinder. As the temperature gets closer to 80 degrees, the number of air molecules stays the same but the water vapor increases. And the bubble expands to keep the pressure at the same level. The ideal gas law was also used when the partial pressure of air in the gas mixture is calculated. This is gotten from number of moles multiplied by the constant and the constant and the whole thing divided by the volume.
Investigating Heat Loss From a Container Planning We are investigating heat loss from a container and how it is affected. We could change: Room temperature Surface area Amount of water Use a lid Insulate around it Colour of tin We could measure / observe: Amount of time Temperature We will change: Surface area We will measure / observe: Temperature (every minute for 5 minutes) Our question is: Does surface area effect the rate of heat loss? We will keep these the same: Colour of tin Room temperature Amount of water Use a lid Insulate around it Preliminary investigation = == ==
take about 30 minutes for the water to cool down 20ºC, which is why I
