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 P€²(T ) for T = 303, 313, 323, 333, 343 by computing the SDQ given by Eq. (4) with h = 10.

Estimate derivatives using the symmetric difference quotient (SDQ), defined as the average of the difference quotients at h and ˆ’h:
