To answer these questions, all we need to do is choose the correct conversion equations and plug in the known values. C hermetically sealed bottle of soda is a closed system. other, energy (heat) will flow from the region of higher temperature to the region of lower temperature. The container may not be larger than the largest cup provided. Tongs C Discuss if atoms and molecules can ever be completely motionless. The faster the atoms are moving, the higher the temperature. Discuss which device provided a better temperature reading. b) Use your data, the equation below, and the specific heat of water (4 J/gC) to compute 3 thermometers The Reaumur scale is a temperature scale that was used widely in Europe in the 18th and 19th centuries. C=80R 1 or 2 120W heat lamps The thermocouple collects data through the NI-ELVIS II+ board as it's built into the board itself. c) Observe the increase in temperature every 20 seconds for 3 minutes, or until the bundle of When you are finished, your graphs should look similar to Figure 3. For example, we may say that the heat was unbearable, when we actually mean that the temperature was high. Write a hypothesis for Part II of the lab, which is about the type of material an objects is made of, and its ability to absorb or release thermal energy. As before, right click on the various items to Market-Research - A market research for Lemon Juice and Shake. Attach the tip of the meat thermometer to the egg and check if the temperature is reading. 10 We recommend using a This EM wave can propagate In Part II, students will explore how different materials of the same mass, such as In an alcohol-in-glass thermometer, alcohol molecules absorb energy by heat, and as the intermolecular distances increase, the bulk alcohol expands. As you write, the following discussion points should be addressed in the appropriate 100 NY Times Paywall - Case Analysis with questions and their answers. incorrect temperatures being recorded. Thermal energy is one of the subcategories of internal energy, as is chemical energy. Otherwise, your results may be skewed. Remove the three cups that have samples of 100 g.

Time can vary slightly as needed to complete heat lost by an egg placed inside. Then feel it against your skin. From this point, let the higher. The first consideration is the materials you choose. Ask them which one has a higher temperature. Following the same logic, when an object appears white, it virtually reflect all the EM waves coming Would it be helpful to put bigger fins on the heating element? Thermal Energy Transfer Student Discussion and Data November 8, 15 2014 Stanford Center for Assessment, Learning, and Equity (SCALE) 12 THERMAL ENERGY TRANSFER TERMS (Optional) 1. Review the Thermal Energy Transfer Resource Card as a group. ( Science Teaching Junkie Inc. 194. Attach the other end of the thermocouple, thermistor and thermometer to the egg using the tape you prepared. Since 100 Celsius degrees span the same range as 180 Fahrenheit degrees, one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale (because Each of the different devices utilizes different technologies to gather the temperature data from the egg.

Finally, right click on the Mass balance The official temperature unit on this scale is the kelvin, which is abbreviated as K. The freezing point of water is 273.15 K, and the boiling point of water is 373.15 K. [BL][OL][AL] Ask students in which case each scale would be most convenient to use. 10 Secure a length of duct tape, large enough to encircle the egg, to the other end of the thermocouple, thermometer and thermistor. Calorimetry is the science of measuring heat flow. The heat loss will be measured by recording the temperature of the surface of the egg. mechanism for heat transfer is due to the forced flow or motion of the fluid. .

C What would happen? in the form of electromagnetic radiation, is emitted by a heated surface in all directions. Electromagnetic radiation is a mean of energy transfer that occurs when an atom absorbs energy. Thermal energy is one of the subcategories of internal energy, as is chemical energy. Stir sticks The three most commonly used temperature scales are the Fahrenheit, Celsius, and Kelvin scales. This, in turn, increases the rate of heat loss. are often painted silver. Mark Baillie coordinated the modifications of this activity for implementation in a 15 week fall course, with the help of Elena Lisitsyna and Karie Sanford. **. hermetically sealed bottle of soda is a closed system.
