WebFeb 5, 2024 · The salt lowers the freezing point of water through a process called freezing point depression. The ice starts to melt, making liquid water. Salt dissolves in the water, adding ions that increase the temperature at which the water could re-freeze. As the ice melts, energy is drawn from the water, making it colder. WebStep 4. Generously sprinkle rock salt all over the ice. Step 5. Insert a thermometer between the bottle and the ice in order to monitor the temperature of the bottle. Step 6. Carefully …
WebFill four cups with six ounces each of tap water. Add a teaspoon of salt to one cup, two teaspoons to another, and three teaspoons to a third. Leave the fourth as your control.
