Question: A Constant-Volume Gas Thermometer An experimenter using a gas thermometer found the pressure at the triple point of water (0.01C) to be 4.80 X l04Pa

A Constant-Volume Gas Thermometer An experimenter using a gas thermometer found the pressure at the triple point of water (0.01°C) to be 4.80 X l04Pa and the pressure at the normal boiling point (100°C) to be 6.50 X l04Pa.
(a) Assuming that the pressure varies linearly with temperature, use these two data points to find the Celsius temperature at which the gas pressure would be zero (that is, find the Celsius temperature of absolute zero).
(b) Does the gas in this thermometer obey Eq. (17.4) precisely? If that equation was precisely obeyed and the pressure at 100°C was 6.50 X l04Pa, what pressure would the experimenter have measured at 0.0I°C?(As we will learn in Section 18.1, Eq. (17.4) is accurate only for gases at very low density.)
