The vapor pressure of water, p(mmHg) is given as a function of temperature, T(C), by Antoine equation: p=10(AC+TB) for T from 1 to 100C where A=8.07131,B=1730.63 and C=233.426. Use Taylor's theorem to approximate the vapor pressure of water with a second order polynomial about T=25C and estimate the upper bound of the error in the valid range of temperature
