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.

Best ResponseYou've already chosen the best response.0The 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
