At the triple point of water, a constant volume gas thermometer measures a pressure of 40 kPa . Determine the pressure measured at the boiling point of water ( 100^ C ).

Step-by-step solution

For a constant volume gas thermometer, the temperature T is directly proportional to the pressure P . T = P P_ tr 273.16 Given that the pressure at the triple point of water is P_ tr = 40 kPa . The boiling point of water is 100^ C , which corresponds to T = 373.15 K . Substituting the values into the equation: 373.15 = P 40 273.16 P = 373.15 40 273.16 P 54.6 kPa
