Polystyrene Heat Lab

Improved Essays
What do your results tell you? Are there any relationships, patterns or trends in your results?

From our [processed] results, we can conclude that the polystyrene cup served as the least effective conductor of heat, the tin mug coming in at a close second. The most effective material for heat conduction was the plastic mug.

At the beginning of the tests, all of the water in the cup declined in temperature at a steady, even rate, but once one minute had passed, they had all started to cool down at very different rates. The plastic trails held the most change, and the water being used for that experiment cooled a lot faster than the other trails; almost two times faster than the water in the polystyrene cup.

The polystyrene and tin mug were very similar; from a standpoint that is observing the cooling rate of the water. They were almost identical in temperature, until three minutes had passed when they both started to cool faster/slower than the other; but even then, the gap between the different temperatures was still extremely close.

Can you explain the relationships, patterns or trends in your results? Try to use some scientific ideas to help explain what happened.

Looking back on the experiment, the equipment used may have had an effect on the test results. For example, the plastic cup had the lowest temperature; this

The main reason why is because of the makeup of the foam. While it is unable to be noticed by the naked eye, polystyrene foam is surrounded by tiny air bubbles (this explain why, although Polystyrene is a porous material, it retains the water heat).. As already proven in the past, air is poor at conducting heat, so it doesn't allow any of the heat from the water to transfer in the Polystyrene. As none of the heat from the water is lost to the cup, the water remains heated, hence why the Polystyrene was left with the warmest temperature at the end of the

    Since the beaker only covered roughly a quarter of the surface area of the hot plate, only approximately a quarter of the thermal energy is transferred to the beaker and by extension the water. The other three-quarters of the thermal energy is transferred to the air. A small fraction of this hot air contacts the beaker before rising which would explain why the calculated energy transferred into the water was slightly over 25% of the total available. This is also demonstrated as the warmer air could be felt around the hot plate during the…

    The objective of the lab was to find the calorie content of Cheetos and marshmallows. To do this we needed to use a calorimeter. The hypothesis was that Cheetos would have more calories because they have more fat in them. The Cheetos and marshmallows were lit and put in an oatmeal can calorimeter. The temputure change in the water leads to finding the calories in food.…

    Comparisons: Effect of crushed vs. whole tablet: The crushed tablet reacted faster because its surface area is smaller, allowing the particles to react faster with the water. The crushed tablet also produced frothy bubbles all over the water, whereas the reaction (bubbles) of the whole tablet was primarily around the tablet in the water. Temperature effect: The reaction was extremely slow in the cold water as molecules do not move as fast in cold water.…

    While the experiment was indeed fascinating to watch, several strengths and weaknesses existed in the research. In the beginning of the episode, Adam and Jamie went to Stanford University to look for a suitable measure for pain tolerance. They were introduced to four standard measures of pain, including extreme heat, capsaicin injection, electricity, and cold pressor test by Dr. Chu, who specialize in pain. After testing out themselves, the hosts of the show chose the cold pressor test (Rees, 2010). Thus, the measurement selected for the experiment is reliable, as it is approved by specialist.…

    I begrudgingly realized I was completing the experiment correctly and resumed my observation of the ice cube by placing a second ice cube into the glass of water. There was an audible sound as the second cube was placed into the water and I was surprised to find the same crackling noise resulting from the temperature differences did not occur with the second cube as it had the first. The tiny air bubbles present during the observation of the first ice cube were not nearly as frequent and immediate. At approximately thirty minutes of observation time I became increasingly frustrated and impatient and began to focus less on the importance of physical observation using my senses, and more of what the importance of the meaning of such as assignment could…

    How Temperature Affects A Glow Stick Glow sticks come in many shapes, sizes, and vibrant colors and are a quite popular object to take to places such as parties. There is one problem with all glow sticks that everyone has to face and that is having it last for an extensive amount of time. The scientific question being asked in this experiment is, how does temperature affect how long a glow stick stays lit? To solve this problem an experiment to see which temperature of the water a glow stick will stay lit longer in will demonstrate this idea.…

    HYPOTHESIS: As the ice cubes melt in the warm water, the melted water from the ice should flow towards the bottom of the cup because the melted colder water is denser than the surrounding water. PURPOSE: The purpose of this experiment is to improve my ability to observe an experiment. In addition, it will help aid me in making proper observations while also drawing conclusions. RAW MATERIALS:…

    Does rock salt effect ice? Rock salt effects the boiling and freezing point of ice. Salt has always helped the roads when it is icy in the winter, but a new idea for the roads may be the use of beet juice. In group A with the little bit of ice and water, that we continued to stir, the temperature decreased from 2°C to .5°C in five minutes.…

    Cool Mints When eating a mint a cool sensation bursts through one's mouth, but is that mint really making their mouth cold, or is it just their mind playing tricks on them? This science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water?…

    The above Time Vs. Temperature graph displays the results of an experiment measuring the time taken for a sodium thiosulphate solution, at a certain temperature, to react with Hydrochloric acid. The descending curve in the above graphs suggests that the higher the temperature of the sodium thiosulfate solution the faster the reaction, causing the cluster of data later on in the graph. This is due to the high temperatures causing the increase in the particles average kinetic energy, the more energy provided by the heat of the water baths the faster the particle within the solution are able to move. As a result of the increased movement the particles are more likely to collide in the correct orientation and cause a faster reaction to occur.…

    This lab was used to discover the specific heat of an unknown metal by using calorimetry. A calorimeter is an object that is used for measuring the heat of reactions or heat capacity of different materials. Specific heat is the heat required to raise the temperature of the unit mass of a given substance by a given amount. Heat over mass times delta T is the equation that is used for finding the specific heat of the unidentified metal (with T being the final temperature minus the original temperature). A sample of an unknown metal was heated to a high temperature, in order to find the specific heat of the said unknown metal the starting temperature of the water in the calorimeter and the boiling water temperature had to be compared to the end…

    Cool water was placed into the calorimeter and its temperature recorded, while an equal weight of water was heated to 35.3 ⁰C. The heated water was immediately poured into the water in the calorimeter and the temperature was recorded. The water equivalent of the calorimeter could then be calculated. Approximately 100 g of cool distilled water was placed into the calorimeter and the initial temperature recorded. Solid sodium sulphate decahydrate crystals of 4.00 g were added to the water in the calorimeter and stirred until it dissolved.…
