Specific Heat Lab

Abstract: The purpose of this lab was to show the different absorption and emission rates of three different substances. Radiation laws, albedo, and specific heat are all reasons why this is achievable. An agreed upon hypothesis is that the sand will absorb the most heat due to the number of molecules, the moss will absorb the second most because it doesn't have as many molecules as sand, but it has more than water, which isn’t as complex. To complete this experiment, you need three beakers of each material, a heat source, a temperature gun, and a timer. Set each beaker under the heat .3 meters off the ground, and collect results every minute. (See attached diagram). In this study the data that was collected proved the agreed upon the hypothesis. …show more content…
The heat source is on a stand .3 meters off the table. See attached diagram for the arrangement of the beakers. We used the temperature gun, so we could find the temperature of the surface. Collect the temperature for each heating material every minute. There will be a table and a graph for each material with 12 minutes of absorption and 12 minutes for emission.

Data and Results: The results showed that the sand absorbed heat at the highest rate, followed by moss, then water. Next, it showed that the sand emitted the greatest amount of heat, followed by moss then water. Our hypothesis was spot on with the results.

Conclusion: The sand and the moss absorbed more heat because it must have a lower specific heat, it doesn’t take long to heat up. The water absorbed the least amount of heat because it has a very high specific heat, so it takes a while before the temperature changes. Water has a low albedo, so it doesn’t give off as much heat and the emission rates are lower. The sand absorbed the most heat, so it emitted the most heat. However, that was not the intended result. The moss was supposed to be the one that absorbed the most. So it is compellingly apparent that something went awry in the conduction of the experiment. Still, the information that was collected is

    In this case, ignore the heat absorbed by the calorimeter. Use the change in temperature in °C, the mass of the water in grams, and the specific heat of water as 4.184 J/(g · °C). This will then put your answer in Joules. Be sure to use the correct number of significant figures in determining the heat absorbed by the water. 9.…

    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…

    To start this laboratory experiment, we first collected all the materials necessary including multiple beakers, samples of each solution, metal strips, a salt bridge, alligator clips, and an abrasive sponge. Then 10 mL of CuSO4(aq) and 10 mL of ZnSO4(aq) were placed into separate 250 mL beakers. A copper strip was then placed in the beaker containing CuSO4(aq) and a zinc strip was placed into the beaker with ZnSO4(aq). The two beakers were connected by a salt bridge that consisted of a string soaked in 0.5 M KI solution and each end was placed into each solution.…

    Catechol oxidase was tested with four different substrates to determine which produced the most benzoquinone. After preparing the spectrophotometer, I added solutions and then I let the substrates react for five minutes. I measured the absorbance of each set by zeroing the blank and testing its corresponding test tube and recording the data in a table. Pyrogallol produced the most benzoquinone and therefore benzoquinone absorbed the most light. My…

    The first experiment had the highest potential energy which is 3786.034 J. The first experiment also has the highest kinetic energy. This was 75552.50572 J. This experiment showed potential, kinetic, and sound energy, friction energy, and heat energy. The marble showed potential energy when it was at the top of the textbooks and the marble showed kinetic when it was rolling down the pool noodle. Potential is stored energy and kinetic is energy that is in motion. When the marble was rolling down the noodle it may have had friction and this could cause heat energy.…

    When dry ice is put into water they start to reacting and boiling. That reaction is called sublimation. Sublimation is when something solid goes straight to gas skipping the liquid phase. So because the water is warm it heats up the dry ice which causes it to form a gas. The gas is carbon dioxide.…

    Chromatin Immunoprecipitation and Sequencing (ChIP-seq) of Heat Shock Factor (HSF) Temporal Binding Sites during the Critical Period of 8-12 Hr After Egg Lay (AEL) in Drosophila melanogaster Embryogenesis Background Heat Shock Response was discovered by the Italian scientist Ferrucio Ritossa, when he saw puffs in the Drosophila polytene chromosome on inducing them with heat. It was later discovered that this Heat Shock Response was regulated by a transcription factor called Heat Shock Factor (HSF). The HSF is responsible for the activation of the Heat Shock Proteins (HSPs) and Heat Shock Cognates (HSCs) genes by binding to their respective promoter region. The HSPs are molecular chaperones that facilitate protein folding, ubiquitin tagging and proteolytic pathways in the cells to prevent the building of proteolytic toxicity.…

    The numbers could have been a lot more exact if the enegery went strait to the water but energy could be lost because the walls are not insulated or warming up the glass holding the water before warming up the water. Another reason the numbers were not perfect was because the food did not burn all the way. If the food burned all the way the numbers also would have been better for doing calculations. To improve this we would need a professional calorimeter with insulated…

    Almost all chemical reactions involve a loss or gain of heat. This change in heat is called enthalpy. The goal of this experiment is to calculate enthalpy for three different reactions. To calculate the enthalpy of a reaction, a calorimeter is used to measure the change in heat energy from mixing different substances. The change of temperature is found by comparing the change in temperature of the system to the temperature of the surroundings.…

    The reason we can use absorbance in place of concentration is because of Beer’s Law, which tell us that the absorbance of a solution is directly proportional to its concentration. For this specific experiment there are two reactants so the pseudo-first-oder kinetics method is needed. This can be accomplished by isolating the effects of the concentration of each reactant from the overall reaction rate. Therefore, by running the experiment with hydroxide in large excess, allowed us to view the effect of only the reactant Crystal Violet. By knowing the two different reaction orders for crystal violet and hydroxide, the rate constant “K” was able to be determined.…

    Laboratory Report 2: Soil Texture, Bulk density and Porosity Introduction Soil Texture The classification of soil texture is determined by the percentage of each of the soil separates. Soil separates are mineral particles smaller than 2mm, and these particles are sand, silt and clay. These textures are separated by the size of the particles, with sand being the largest between 2mm and 0.05mm, silt at between 0.05mm and 0.002mm, and clay at <0.002mm.…

    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.…
