An experimenter using a gas thermometer found the pressure at the triple point of water $(0\mathrm{.}01$C$$C$)$ to be $4\mathrm{.}80104$Pa$4\mathrm{.}80104$Pa and the pressure at the normal boiling point $(100$C$$C$)$ to be $6\mathrm{.}50104$Pa$6\mathrm{.}50104$Pa$.$If that equation were precisely obeyed and the pressure at $100$C$$C were $6\mathrm{.}50104$Pa$6\mathrm{.}50104$Pa$,$ what pressure would the experimenter have measured at $0\mathrm{.}01$C$$C$?$
