Thermometer Essays

and placed slightly below the rim of one cup. The cup with the cardboard lid was stacked inside the other cup. A hole in which the thermometer could fit snugly was poked into the cardboard lid, and aluminum foil with a hole of the same size was placed over the cups to provide extra insulation. The commercial calorimeter provided for the experiment and two thermometers were also

Babies R Us LED Whale Bath Thermometer- http://amzn.to/2HtRmoq Babies R Us bath thermometer shows the temperature on the LED display at the top. If the water is above 100 Fahrenheit or below 90 degrees, the display flashes. The bath thermometer is activated by water, turns off automatically when removed in the water and re-reads the temperatures after every 5-second. It has a dimension of 4 x 2.5 x 2.5 inches and requires 2AA battery which is included in the package. This floating has an eye-catching

What was the reason for each one?1) Microscope-used to watch microbes. 2) Mercury indicator used to quantify barometrical weight. 3) Fahrenheit thermometer-used to show water solidifying at 32 degrees. 4) Celsius thermometer-used to show water solidifying at 0 degrees. How did the thoughts of Hobbes and Locke contrast? Hobbes communicated thoughts in a work called Leviathan. He trusted people were actually egotistical and shrewd

The Galileo Thermoscope In 1603 there was an invention that changed how our society works. Thermometers gave us a sophisticated understanding of heat. Thermometers are used almost everywhere, doctors use them, people in the weather industry use them, it is so efficient it is even used by your parents to immediately check if you have a fever. They are more efficient and reliable than measuring temperature with a hand or using your feelings to tell the weather. But how did this amazing invention come

a hot plate with a thermometer. This beaker’s temperature needs to stay constant at 60℃ so the hot plate settings may need to be adjusted throughout the lab. Next, fill the 1000 mL beaker ⅔ full with cool tap water (roughly 700mL full) and place a thermometer in it. Set this beaker aside and maintain a temperature of roughly 25℃. Place the test tube of benzoic acid/lauric acid in the 60℃ water on the hot plate and when the solid solution begins to melt place the thermometer that was in the water

elements would be one of the following: Al, Bi, Cd, Cu, Fe, Pb, Ni, Na, Sn, or Zn. First the specific heat of water was measured, then heat flow was measured using equations. Then, using two coffee cups, observe the temperature increase from the first thermometer in the calorimeter. After it has stopped increasing, record the final temperature. Next, weight a small portion of your unknown sample and record the mass and place it in the water bath for ten minutes and record the temperature. Pour the unknown

Potassium Chloride Lab Report - Seya Introduction The reason why we chose to test the solubility of 50ml of water at various temperatures is because KCL is known to have constant data and therefore leads to better results. The solubility of potassium chloride in water is due to ion-dipole interactions. Research Question Time needed for (2g) Potassium Chloride to fully dissolve compared to the temperature (20°C - 70°C) of the (50ml) Water. Theory and Background Both the quantity of KCl added to

looking daily at the thermometer, which is filled with mercury. What L.P. Hartley symbolises with the thermometer is the heat of the relationship between Marian and Ted, one which Leo is unknowing of. Leo is waiting for the thermometer, between himself and Marian to rise significantly, which is why he checks the thermometer daily for a rise in temperature. “The thermometer stood at 84.” “But I was confident it could do better.” This shows the dedication of Leo to the mercurial thermometer . His twelve year

Through this experiment, getting the best container to be used is determined. Using a thermometer, this was very conventional. It made getting of results easier rather than feeling the heat with hands. The temperature was written on a paper and the average temperature was known. Four different types of soup containers. The containers used

However, if you are checking someone’s temperature by placing the thermometer under their tongue, you are adding heat to the thermometer, which in turn heats the mercury to give you a reading to determine whether or not they have a fever. This is also true when you run a thermometer under hot water from a faucet. Helium is a gas that is used in balloons. As long as you keep the temperature constant or continue to add heat

experiment I used the ideal gas law; pV=nRT. In this experiment I began each trial by measuring the temperature of the water, then I found the volume of the gas by using displacement. I used a plastic “ziploc” bag as the gas container. I then used a thermometer and scale to measure the pressure

12. I will put the thermometer into the beaker and stir the water, leave the thermometer till the temperature stays constant.-this will give the normal water temperature. 13. I will take the water out the beaker and wipe it dry. 14. I will activate the heat packs wait for a minute put thermometer onto the copper to see the temperature 15. I will then pour water into the beaker to 500ml. 16. I will put the thermometer into the beaker and stir the water, leave the thermometer till the temperature

attempting to determine whether a reaction took place using prior knowledge of indicators that determine the presence of a chemical reaction. Materials: Safety goggles Aluminum foil Beaker 50 mL of distilled water Copper (II) Chloride (CuCl2) Thermometer Scale Discussion: In chemistry, a chemical reaction is the process by which one or more initial substances change into a new substance through a process of chemical changes. There are multiple indicators that a chemical reaction has occurred such

Catalase Experiment Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Independent and Dependent Variables Independent Variable: The independent variable is the chicken liver and the potato. Dependent Variable: The dependent variable is what I will be measuring which is how much peroxide I will use for each individual experiment. I will also need to measure the temperature of the peroxide during/after the experiment and the pH balance. Purpose “What was

Science of Sweat Experiment Evaluation This experiment aim was to explore how sweating affects the human body, through a model of this process, with the body being represented as a test tube filled with warm water and the skin represented as a paper towel covering the test tube. The independent variable was the state of the paper towel; a wet, a dry, and none. The independent variables were considered the different tests tested. The strengths of the method used include the controlled variables of

Statement of Problem: Using a thermometer with graduations above 40ºC covered, construct an experiment to find the temperature of the water found in a coffee pot which simulates a water heater that can be heated to 55ºC. Hypothesis: If the temperature of 50mL of tap water is found and then mixed with 25mL of hot water, then the temperature of the hot water can be determined because by finding the final(mixture of hot/tap water) and initial(tap water) temperatures, the experimenter can discover

tightly by the cork carrying the test thermometer. The position of the cork and the thermometer was adjusted so that the cork fit tightly, the thermometer and the jar were coaxial, and the thermometer bulb resting on the bottom of the jar. The test jar was places in the ice box containing freezing mixture. In the determination of the cloud point the sample was cooled and inspected at intervals of 2°C until a cloud and haze appeared, than noted the thermometer reading. This was the cloud point. As

Josie Krueger March 22, 2023 Title: An Inquiry into the Effect of the Molarity of Salt Water on the Boiling Point Word Count: 984 Overview: This lab was an inquiry into the relationship between the molarity of saltwater and its boiling point. Testing in this lab consisted of four separate molarities, along with three trials per molarity. The lab modeled a form of chemical reaction called ionic bonds, and highlighted common chemical reactions in life. Testable Question: How does the

Some of the factors are thermometer was calibrated to determine its precision. The actual melting points of water, phenylacetic acid, o-anisic acid, and benzilic acid to their observed melting points were determined by calibrated thermometer. Then the solubility tests were run in order to determine the appropriate solvent for the unknown solute (Table 1). After determination of a solute

In this experiment three of the system variables, water temperature, air temperature, and air flow, were changed and compared to a base trial, Trial 1. The variable that effected the system the greatest was temperature. The data collected from this experiment indicates that the most efficient cooling occurs when there is a larger difference between the water and air inlet temperatures. Trial 1, heated water with unrestricted air flow at room temperature, had the largest change in temperature of the
