Question

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 help

Answer 1

1.- convert all the temperature values from C to K
K=C+273

2.- divide each of the pressure by the temperature in K
3.- calculate the average of the P/T calculated in (2)
4.- multiply the 150C converted to K by the average of the P/T calculated in (3)

Answer 2

Volume is constant

Answer 3

You need to use this \[\frac{ P_{1} }{ T_{1}} = \frac{ P_{2} }{ T_{2}}\]

Answer 4

as @cuanchi said you must convert the temperature from celcius to kelvin.

Answer 5

\[\frac{ P_{1}*T_{2} }{ T_{1}} = P_{2} \]
