Question

A student collected the following data for a fixed volume of gas:
￼
Temperature(C)      pressure(mm of hg)
  10                                726
  20                                750
  40                                800
  70                                880
  100                              960
  150                               ???

Fill in the missing data point.  Show all calculations leading to an answer.

bobpursley · Answer

pressure is directly proportional to temp in Kelvins. So change temps to K

emperature(K) pressure(mm of hg)
283 726
293 750
313 800
263 880
393 960
423 ???

Now do a proportion
PPP/423=960/393

check all my temp conversions, solve for PPP
