Which aspects of the competition formula are most advantageous? In this lab, we will focus on the ways heat is transferred. Now double click the DAQ.py to run the python script. Insert the other end of one of the resistors into the AI 7+ (row 15), and the end of the other resistor into AI 7- (row 16). 3. the other two cups, filling one with 200 g of wet sand and one with 200 g of dry sand. Students can use the process described in this video as a means of comparing different temperature scales. Record this initial temperature for the three metal samples in Table B. b) Raise the thermometer and lid off the calorimeter, and carefully transfer the bundle of heated R Draw and label a diagram of an area where land and ocean meet and one where the opposite type of location is shown. source data for performing necessary calculations. Assume that the copper will have the same initial temperature in each trial. the mass of the metal and is the decrease in temperature of the metal. Variables Independent Variable: type of substance, Controlled Factors: mass, initial temperature. For example, we may say that the heat was unbearable, when we actually mean that the temperature was high. Your teacher may provide a copy, or you click the link to access it. If you are redistributing all or part of this book in a print format, Temperature is the measure of the average kinetic energy of atomic motion. The first consideration is the materials you choose. An ideal Thermos is an isolated system. Faster moving molecules have greater kinetic energies, and so the substance has greater thermal energy, and thus a higher temperature. describe how the macroscopic properties of a thermodynamic system such as temperature, specific heat, and pressure are related to the molecular level of matter, including kinetic or potential energy of atoms; analyze and explain everyday examples that illustrate the laws of thermodynamics, including the law of conservation of energy and the law of entropy.
