A constant volume thermometer indicates a pressure of 1.500 10⁴ Pa at the triple point of water, while at the normal boiling point it indicates 2.050 10⁴ Pa . Determine the temperature at the normal boiling point.

Step-by-step solution

For a constant volume gas thermometer, the temperature T is given by the relation: T = T_ tr P P_ tr where T_ tr = 273.16 K is the temperature at the triple point of water. Given: P_ tr = 1.500 10^4 Pa P = 2.050 10^4 Pa Substituting the values: T = 273.16 2.050 10^4 1.500 10^4 T = 273.16 205 150 T = 273.16 41 30 T = 373.318 K Rounding off to one decimal place, we get 373.3 K .
