(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

P(at triple point in torr of water) 100 200 300 400

P(in torr for gas w/ respect to Pressure above) 127.9 256.5 385.8 516.0

The previous table gives the observed values of the pressure of a gas in a constant-volume gas thermometer at an unknown temperature T and at the triple point of water as the mass of the gas used is reduced. Determine T in kelvins by considering the limit of the pressure of the triple point as it approaches zero of (P(gas)/P(triple point of water).

2. Relevant equations

P=aT+b

T(K)= 273.16lim(Ptp->0)(P/Ptp)

3. The attempt at a solution

I don't even know where to go with this. I have no clue where to start. I've tried a bunch of random things, but it all goes nowhere.
