Chips in altitude
Have you ever seen an expanded bag of potato
chips up in the mountains?
If you have, did you ever wondered how fast this
expansion process happens?
We set out to answer that question

Results

• We took three tests each at 500 and 1000 ft.
• Our predictions We predicted that at 1000ft
  600ml of air would expand 22mL and at 500ft 11ml
• These are our results At 500ft the air expanded
  an average of 4.67ml, and at 1000 it expanded an
  average of 6.83ml

Analysis

• Reasons for discrepancies
• As time progressed temperatures rose
• Evaporation
• Shaking gondola
• Changing of previously expanded air
• Leaks in gondola
• Slow mastery of procedure
