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.

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
1025 ?
