Background

• Purpose
• To record differences of temperature with
  different altitudes.
• Why is this important?
• Possibly to predict, the differences when
  climbing a mountain.
• Or the different temperatures any different
  altitudes that one can physically rise to.
• Also to examine global warming, and how much
  difference there is in the temperature, from the
  past.

Hypothesis/Tests

• As the gondola rises with altitude, the
  temperature will decrease until the peak.
• We will be raising a gondola 1000 feet in the air
  with a surface temperature sensor to examine the
  difference in the temperature with the increasing
  altitude. We stopped every 100 feet to take
  measurements of the height (due to slant caused
  by the wind).

More Data
Both linear fit slopes were equal and negative,
showing a decrease in temperature.

Conclusion

• Our hypothesis was validated. As the gondola rose
  in altitude the temperature decreased. This can
  be logically reasoned as pressure is related to
  temperature by the ideal gas law. Because the
  data fits were not taken at the same time, the
  sun caused a constant offset between the linear
  fits (a trend line).
