A student collected the following data for a fixed volume of gas:
Temperature (⁰C) 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.

Best ResponseYou've already chosen the best response.0we know for a fixed volume the no. of moles is also fixed. SO in PV=nRT equation V , n and R is constant ( R is universal gas constant so it is anyways constant ) So we can say that \[P \alpha T\] Pressure is directly proportional to the temperature. \[\frac{ P _{1} }{ T _{1} }= \frac{ P _{2} }{ T _{2} }\]

Best ResponseYou've already chosen the best response.0So use one set of known of data and the unkonwn set like this ! P1/T1=P2/T2 So let's say that the unknown pressure is P1 then P1= P2 x T1 /T2

Best ResponseYou've already chosen the best response.0If we use the 1st set of data given ! P1= ? T1= 150 C P2 = 726 T2 = 10
