In Problem, plot the given points, draw the line that best fits the data, and use the slope and/or y intercept to determine the quantity wanted.

The relationship between the vapor pressure P of a liquid and its absolute temperature, T, is given by the Clausius-Clapeyron equation,

where AH is the molar heat of vaporization of the liquid and R is the ideal gas constant, 1.987 calories degree−1 mole−1. The following data were found.

What is the molar heat of vaporization of the liquid? [See Problem 65.]

Problem 65

In Problem, plot the given points, draw the line that best fits the data, and use the slope and/or y intercept to determine the quantity wanted.

Find k of y = kx2. [Hint: Substitute z = x2 and graph y = kz.]
