A constant-volume gas thermometer is calibrated in dry ice (that is, carbon dioxide in the solid state, which has a temperature of -80.0°C) and in boiling ethyl alcohol (78.0°C). The two pressures are 0.861 atm and 1.569 atm.
(a) What Celsius value of absolute zero does the calibration yield? (Express your answer to the nearest 0.01°C.)
So I'm given this T= T1-p1X(T2-T1/P2-P1)= -273.47
The Attempt at a Solution
I understand the equation and it works with the values that are given however i don't get what exactly the question is looking for if someone can clear it up i would really appreciate it :shy:
