cacture Explora C in a test liquid? f AppastParameters Data Collection Siirt Soort Capenental La Apparatus 12000 Heat Transfer Heat represents our conception of a form of energy that is proportional to temperature. For the same object, higher temperatures mean that it contains more heat or more heat energy to be precise. International, Inc. In this lesson you will observe heat being transferred through an aluminum bar between two calorimeters by measuring the temperatures over time in them. You expect the hot liquid (on the left) to cool down and the cold liquid (on the right) to warm up You might ask how much the temperatures would change without the aluminum bar connecting the calorimeters. Another question could be how the temperature would change if you removed one of the calorimeter cups and just wrapped that end of the bar with insulating tape. Would insulating the exposed portion of the bar affect your results significantly?

lab.com Luxation (PC re rise in a test liquid? the f 9 Sexp Da Grap The most significant random error involves reading the temperatures accurately. Use care in taking data Systematic errors arise from heat loss, from inaccurate measurement of the amounts of liquid, and from poor calibration of the thermometers Graphs Your graphs show the temperature plotted against time. For increasing temperature, the points will move upward to the right. For decreasing temperature, those points will move downward to the right Units of Data Units for Temperature Temperature values are in units of degrees Celsius ("C) or kelvins (symbol: K), One hundred degrees Celsius and 100 kelvins both separate the freezing point (0°C) and boiling point (100°C) of water. However the kelvin is defined as defined as the fraction 1/273.16 of the thermodynamic (absolute) temperature of the triple point of water. The relationship between Celsius and kelvin scales is given approximately by 0°C-273.15 K EXPLAIN Units for Time The time values you collect in this lab are in units of seconds.
