An experimenter using a gas thermometer found the pressure at the triple point of water (0.01°c) to be 4.80 × 10⁴ pa and the pressure at the boiling point (100°c) to be 6.50 × 10⁴ pa. 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). pay attention to the number of significant figures. the triple point temperature is an exact number.
