With P(T) as in Exercises 71 and 72, estimate P(T) for T = 303, 313, 333, 343, now using the SDQ.

Data From Exercises  71

The vapor pressure of water at temperature T (in kelvins) is the atmospheric pressure P at which no net evaporation takes place. Use the following table to estimate the indicated derivatives using the difference quotient approximation.

Estimate P'(T) for T = 293, 313, 333. (Include proper units on the derivative.)

Data From Exercises  72

The vapor pressure of water at temperature T (in kelvins) is the atmospheric pressure P at which no net evaporation takes place. Use the following table to estimate the indicated derivatives using the difference quotient approximation.

Estimate P'(T) for T = 303, 323, 343. (Include proper units on the derivative.)
