Thermos Insulating Hot Water

The dependent variable in the experiment was the temperature and energy absorbed by the water.

The water was transferred to a 400mL beaker. The beaker was transferred to a hot plate to boil the water. A Styrofoam cup, a plastic pipette and a scale were used to measure about 150g of room-temperature deionized water. The water was transferred to the coffee cup located in the calorimeter. The initial temperature of the water was measured using a thermometer, which was allowed to equilibrate with the water for a few minutes first and then the temperature was recorded.

This also demonstrates the exothermic nature of the mixture, although there is a relatively small increase in temperature. The graphs demonstrate the rapid escalation of temperatures in the first ten seconds, then the gradual increase for the next two minutes. On average, 73.7% of the temperature increase occurred in the first ten seconds of the experiment, however, this percentage was affected by the appearance of a significantly higher outlier in the data set, therefore, this average would lower with an increase in data

Next, we put the foil in the box, then put foil around the box, and lastly put some plastic wrap around the burrito. If you want to do the project yourself here are the steps 1. Get 2 burritos 2. measure the temp of both 3. Put one in our device 4. put one in nothing 5. wait 5 minutes 6. measure the temp of the burrito in our device 7. measure the temp of the burrito with no device 8. do this 2 more times 9. see if our device if it worked 10. eat the burrito, all of it. Here is the data from our test. 0 minutes = 60 degrees, 5 minutes = 60 degrees, and 10 minutes = 60 degrees. Here is the data from the control. 0 minutes = 65 degrees, 5 minutes = 55 degrees, and 10 minutes = 45 degrees. A few things we would change are we would wrap the burrito so less of it's thermal energy moves and make sure that the thermal energy does not come out of the box. Our invention worked, we know this because the initial temperature was 60 and the final temperature was 60 so this proves that our invention worked. The reason why this proves that our invention worked is that the control started at 65 but went down to

One of our flaws was that the temperature of the water was not exactly the same when we did the different trials. The temperatures were slightly off from our recorded value during the experiments. The change in temperature would affect the time it took for the Alka-Seltzer tablet to dissolve in the water. If there was a direct relationship between water temperature and dissolve time, we would not be able to see it because the temperatures are off and the dissolve times are not associated with the correct temperature. Another flaw is that we did not use the same amount of water throughout the experiment. We used a beaker to measure the water, which did not result in accurate measurements. The difference in amount of water could result in a difference in reaction time. The third flaw in the experiment was that during the reaction of the warm water, the water in the cup overflowed and spilled, bringing some of the Alka-Seltzer tablet with it. There were different amounts of tablet in different areas of the water, which means a different amount of Alka-Seltzer remained inside of the cup in each trial. This difference would mean that data for the warm water would fluctuate and we would not have accurate

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

For our lab, we have six beakers of water. Three of the beakers contain high temperature water that range from 46 ℃ to 55 ℃, while the other three beakers contain room temperature water that range from 22 ℃ to 23 ℃. Then, we take six different colored Alka Seltzer tablets, and place them into the beakers one at a time. We record the length of time it takes for each Alka Seltzer to dissolve

Question: Will changing the water temperature affect how quickly a gummi bear dissolves in water? Hypothesis: If the temperature of the water is warmer, then the gummi bear will decrease more quickly in size than compared to cooler temperatures. Materials: Gather the following materials including: •safety equipment including: goggles, gloves, and apron •two 25 mL beakers •one graduated cylinder •one thermometer •one hot plate •8 red gummi bears from the same brand •20 mL of normal tap water in each beaker •one balance measured in grams •forceps •paper towels Procedure: 1.Gather all the materials listed above. 2.Include data tables in your experiment by doing two trials.

Objective The objective of this experiment is to study the effect of varying temperatures on the enzyme catalase by measuring the oxygen production as it breaks down hydrogen peroxide. Introduction Enzymes are used in our daily lives in many ways. From industry to agriculture, enzymes play a necessary role in everything from bread to laundry soap.

We kept our experiment reliable and accurate by having a thermometer in the beaker the whole time and letting the thermometer cool down between each experiment.

In an article called “Heat Transfer by conduction” by Mike Brown, it states “Thermal energy in the vibrating particles or molecules is passed on to nearby particles in a process called conduction”. This explains to us the process of conduction in which it relates to our design because when we insert the thermometer into the warm water, our goal is to keep the water warm with our cup so that once the thermometer makes DIRECT contact with the warm water, it will heat up the thermometer and give us an exact temperature.

In the experiment we concluded that room temperature had the longest duration and that the hypothesis that the hot temperature water would last longer was terribly wrong. The hot temperature water had the shortest time, and in all three trials it did not last longer that 3 and a half minutes. The room temperature water had an average time of 13 minutes and 43 seconds and the cold temperature water had an average temperature 13 minutes and 44 seconds. The cold temperature water had one second longer duration than the room temperature this is because in the 3rd trial the cold temperature water lasted over 15 minutes. Since there is no way to determine exactly when the light stops glowing the times can vary and this affected the averages. The

Update: Teplo denied my refund. I have no issue with their denial of my refund. I base this on the fact that Indiegogo is not a shop, but rather a platform for funding innovation. That being said, I believe the Teplo Indiegogo campaign page alluded to the notion that the Teplo device would heat the initial water. The campaign page states, "Instead of letting your tea get cold, a rechargeable battery hidden in the base of the bottle keeps the beverage at the preferred temperature for as long as 4 hours." However, this does not implicitly imply Teplo could not heat the original water. Furthermore, in the section "HOW IT WORKS", no mention of the need for the initial water to be hot exist. These steps include selecting the tea followed by the next step: "The app will notify you when to put the tea leaves at the right brewing temperature." Followed by more steps before reaching the final step: "After the drinking temperature is reached the

The two testing methods we used were to find the temperature inside of my product and the marshmallow that was inside of my product. The first testing method was to use the thermometer to record the temperature of the marshmallow as measured in degrees celsius at 5,10, and 15 minutes. I predict that the marshmallow will have the highest temperature after 15 minutes. The second testing method we used to determine if our device worked was to record the temperature of the box itself in degrees celsius at 5,20, and 15 minutes. I predict that the temperature will be the highest at 15 minutes. The testing method I think best represents my device is the recording the temperature of the marshmallow due to the fact that it my product of going to be

To achieve this, the final value from each thermocouple was set to be equal to the warm water bath temperature (370C), and the initial reading was set equal to the ice water bath temperature. Thus, for each thermocouple an equation was obtained using the two points to convert voltage readings to temperature. An example of the calibration for one of the thermocouples is shown in Appendix II.
