Reply to comment by RockinRobin-69 in What are the effects of adding rock salt to a cooler full of ice? by Ok_Kareem_7223

That is not what is happening at all. They both have same amount of ice. One has salt that improves the transfer of heat from the environment to the ice.

Salt lowers the freezing point of water. This causes some of the ice to melt. The melting requires heat energy and this makes the solution drop in temperature.

Take two bowls and put an ice cube in each. Add salt to one. Watch.

Edit cure to cube

True, and now the entire surface area of the water is cooling the environment faster at a lower temperature.
