supposedly, adding salt to water raises the boiling temperature---thereby the
water absorbs more heat than pure water at 100 C.

conversely, adding salt to water will lower its freezing temperature---why
salt is spread on roads to lower freezing temperature to keep vehicles from
sliding on ice.

How to prove? Heat two beakers, one plain and one heavily salted and
measure temperature peak. Fresh = 100 c, salt water is greater.

on the back side, have two beakers of heavily iced water, fresh measures at
about 0 C and salt water will go below -10C

Easy to do with proper safety precautions.
