The Unsteady State Heat Transfer Experiment Essay

In this experiment, two Styrofoam cups and a brand calorimeter are each used to calculate heat transfer. The results will be compared to see if the something as simple as a Styrofoam cup can be used accurately as a calorimeter and produce efficient results. Using hot and cold water, the Styrofoam cup and brand calorimeter will be used to determine the heat capacity. By using the mass of the water, specific heat of water and the change in temperature, the heat capacity will be determined. The brand calorimeter and Styrofoam calorimeter

3. Convection the transfer of heat through currents of gases or liquids. (occurs passively as warmer air at the surface of the body rises away from the body and is replaced by cooler air – process is aided by wind or fans)

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

Compare heat transmission in different materials (e.g., conduction of heat in different solids, absorption of radiant heat by different

8. Thermoregulation is keeping the temperature of an object in this case the human body stable or in a controlled temperature.

The hypothesis is that two people of different sizes will have a different temperatures after preforming an activity, this was proven after collecting data from the experiment. The first thing that was noticed in this experiment was the difference in Darryl and Faith's thermal mass temperatures. When looking at the data chart Darryl’s core body temperature was a few degrees higher than Faith’s. The temperatures were taken by using a surface thermometer stick. After the exercises were completed it was shown that after one of the exercises Faith's thermal mass was higher than Darryl's. The exercises that Faith's thermal mass exceled in was when her and Darryl were running up and down the stairs. When running up and down the stairs at different

The second experiment involved the heat exchange between metal and water. The metal in beaker and water in calorimeter

What I learned from this lab is that when you put metal in hot water it does not go up alot the Initial temperature was 23.8 degrees and once we put in the metal it was finished we took the temp and saw the final was 23.9 degrees. That did not go up pretty much it went up like .1 degrees.

Thermal energy is a component of life that affects everything that we do and how things react. The three forms of heat, which are conduction, convection, and radiation, can be seen in scientific studies but play a role in day to day life. Science can reach beyond the walls of research and can be seen in day by

In the Stockroom, click on the Glassware tab and select a 250 mL Erlenmeyer flask. It will appear on the lab bench.

The purpose of this experiment was to determine the specific heats of three different metals by reading the temperatures of the water with a water-boiled metal immersed in it. Methods employed included weighing items on electronic balances, boiling water using a bunsen burner, recording temperatures, and doing calculations. EXPERIMENTAL PROCEDURE For this laboratory experiment, we used water, three cubes of different metals, a bunsen burner, a ring stand, a thermometer, electronic balances, beakers, and a styrofoam cup.

Thermal energy is the energy a substance or system has related to its temperature. This means the energy of moving or vibrating molecules. Atoms and molecules are always in motion. Generally the motion of thermal energy cannot be seen, but instead the effects it has on the substance can be seen or felt. Thermal energy can have several different uses. It can be used to heat homes, cook food, and generate electricity.

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.

Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems, design of conventional space and water heating systems, cooling of electronic equipment, and many manufacturing processes (Campos 3).
