Question

all calculations leading to an answeA 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 r.
help please

Answer 1

The General Law of Gases states that
P1*V1/T1 = P2*V2/T2.
As Volume is constant, we can write this as
P1/T1 = P2/T2,
P1 and T1 are the pressure and temperature at time 1.
P2 and T2 are the pressure and temperature at time 2.
You can take any pair of values as P1 and T1 and find P2 = P1T2/T1, once you sum 273.15 to each temperature to get kelvins.

P1 = 726 mm Hg
T1 = 10 + 273.15 = 283.15 K;
T2 = 150 + 273.15 = 423.15 K.
Then, P2 = 726 * 423.15/283.15 = 1085.96 mm Hg 10,726 ) , (100, 960)
slope is (960 - 726) / (100 - 10) = 2.6
y = 2.6 x + b
find y intercept
726 = 2.6*10 + b
726 - 26 = b
700 = b
y = 2.6x + 700
this means in celsius , pressure = 2.6 * temperature + 700
now plug in x = 150
y = 2.6(150) + 700 = 1090 I got so far

Answer 2

but it said my answer was wrong
