Note: the ASCII code for the degree symbol is alt-248 (hold down the Alt key and type 248) Practice Problem #2 The volume of a gas decreases as the temperature of the gas decreases. A sample of gas was collected at 100 degrees Celsius and then cooled. The changes in the volume of the sample are shown below. T ( C ) V (ml ) 100 317 80 297 60 288 40 278 30 252 20 243 10 236 0 233 10 227 -30 202 1. Graph the data, but make sure that your y- and x axes allow you to extrapolate the trend line to reach a gas volume of 0 mL. Think about what this means. 2. The temperature at which the volume of the gas reaches zero is the theoretical temperature of Absolute Zero. Based on your graph and your extrapolated best fit line, predict the Celsius temperature for Absolute Zero
