The normal boiling point

T_N

is the temperature at which the vapour pressure of a liquid equals

1\ \mathrm{atm}

, and the standard boiling point

T_S

is the temperature at which the vapour pressure equals

1\ \mathrm{bar}

. Which statement is not correct for water? (1)

T_N=100^\circ\mathrm{C}

(2)

T_S>100^\circ\mathrm{C}

(3)

T_S<100^\circ\mathrm{C}

(4)

T_S<T_N
