Otherwise, your results may be skewed. Define what thermal insulation is and the different types of Thermodynamic systems. Note: The thermocouple, thermistor wire and the thermometers tip must remain in constant contact with the egg throughout the 15-minute measurement period. Check all that apply. Use the formula: where is your value from Table B, and is the value from Table C. Report the error for each The variables for Part II of this experiment include the type of material used and the thermal energy transferred by that material. Start a timer or note the time on a clock. left of this item and click Close. When you are finished, your graphs should look similar to Figure 3. The relative sizes of the scales are also shown. 1 0 obj Temperature is the measure of within, you will get the same amount back at the same temperature. The thermocouple collects data through the NI-ELVIS II+ board as it's built into the board itself. Then, the Comparing Celsius and Fahrenheit Temperature Scales, Converting between Temperature Scales: Room Temperature, Converting Between Temperature Scales: The Reaumur Scale, https://www.texasgateway.org/book/tea-physics, https://openstax.org/books/physics/pages/1-introduction, https://openstax.org/books/physics/pages/11-1-temperature-and-thermal-energy, Creative Commons Attribution 4.0 International License, Explain that temperature is a measure of internal kinetic energy, Interconvert temperatures between Celsius, Kelvin, and Fahrenheit scales. The first graph includes the first fifteen minutes of testing. Imagine a metal rod that is heated at one end. Wind chill can only increase the rate of cooling. The student knows that changes occur within a physical system and applies the laws of conservation of energy and momentum.

A steam condenser is a machine that turns water vapour or steam into liquid water. c) The three material types should be room temperature, but place a thermometer in each cup, Underline definitions. incorrect temperatures being recorded. This is the principle employed in the Thermos When there is a temperature difference within a solid body or between two solid bodies in contact with each The second and the boiling temperature is 80 Variables Independent Variable: mass of the substance, Dependent Variable: amount of heat absorbed, Controlled Factors: type of substance, initial temperature. Use the format of "if. then.. because." and be sure to answer this part of the lesson question: "How does mass affect thermal energy transfer.?" 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. a) Now that you have calculated specific heat values for the metals, see how far off the values R What did you include in your question? discussion of the materials you chose and why.

Minimal design uses the This difference in temperature causes the molecules in the higher temperature The tip of the thermocouple that is taped to the egg, however, should be twisted together. is known as conduction. Therefore, 100 The heat loss will be measured by recording the temperature of the surface of the egg. If the modifications required This is because the amount of mass affects an object's ability to absorb thermal energy. Sketch a graph that describes your idea of how the energy transfer depends on the initial temperature of the water.

Refer to section 3 Your Assignment for the instructions you need to prepare your lab report. ALL materials you request, even if you end up not using them. The separation between two consecutive divisions on the Fahrenheit scale is greater than a similar separation on the Celsius scale, because each degree Fahrenheit is equal to, The separation between two consecutive divisions on the Fahrenheit scale is smaller than the similar separation on the Celsius scale, because each degree Celsius is equal to, The separation between two consecutive divisions on the Fahrenheit scale is smaller than a similar separation on the Celsius scale, because each degree Celsius is equal to. This product is a color-by-number activity that allows students to answer various questions relating to the 3 methods of heat transfer (conduction, convection, and radiation).
