For the following solute/water systems give the new boiling point or freezing point. (three sig. figs. plz) Boiling point?
a) 0.75 m NaCl
b) 3.00 m C6H12O6
c) 2.4 m Na3(PO4)
Freezing Point
d) 1.35 m KCl
e) 2.5 m CH3CH2OH
f) 0.58 m K2(SO4)

Why doesn't heat added to water make the tempature rise above 100c
