Boiling+Point+of+Water+-+Using+Your+Graphs

26) Open the graph of boiling temperature versus atmospheric pressure. Use the Analyze Menu > Interpolate feature to help you answer **questions M & N** on your worksheet:
 * Based upon the boiling temperature of water at Yellowstone Lake, what was the atmospheric pressure that day?
 * Based upon the boiling temperature of water on top of Grand Teton, what was the atmospheric pressure?

27) Insert a text annotation box on the graph at each of the above points and label them as:
 * Pressure at Yellowstone Lake (and include the pressure value)
 * Pressure at Grand Teton (and include the pressure value)

28) Print a copy of the graph of boiling temperature versus atmospheric pressure. Turn this graph in with your worksheet.

29) Open the graph of boiling temperature versus altitude. Use the Analyze Menu > Interpolate feature to help you answer **questions O & P** on your worksheet:
 * At what temperature would you expect water to boil in Lutz, Florida (elevation 62 feet... yes it is a real city!!!)?
 * According to your data will water boil at 100°C at sea level?

30) Label each of the above points on your graph. 31) Use the slope formula and data presented to answer **question Q**:
 * At what temperature would you expect water to boil at Death Valley (elevation -282 feet ... that's below sea level)?

32) Print a copy of the graph of boiling temperature versus atmospheric pressure. Turn this graph in with your worksheet.
