Is the freezing point of sugar water and brine the same as that of pure water? Why? Design of experimental verification Is the freezing point of sugar water and salt water the same as that of pure water? Why? Design an experiment to verify
Not the same.
The density and specific heat of the three substances are different
First put the three in the refrigerator (at the same temperature) to make them solid, and then adjust the temperature of the refrigerator (at the same temperature) to see which one melts quickly
