The following is a set of data for the vapor pressure of ethanol taken by a physical chemistry student. Plot these points by hand on graph paper, with the temperature on the horizontal axis (the abscissa) and the vapor pressure on the vertical axis (the ordinate). Decide if there are any bad data points. Draw a smooth curve nearly through the points. Use Excel to construct another graph and notice how much work the spreadsheet saves you.

Temperature (^◦C) .......................Vapor pressure (torr)
25.00 ..........................................................55.9
30.00...........................................................70.0
35.00 ..........................................................97.0
40.00 ........................................................117.5
45.00 ........................................................154.1
50.00 .......................................................190.7
55.00 .......................................................241.9
