Question

maureen adds a spoonful of salt to a glass of cold water.
which of the following would help the salt dissolve fastest?
◯ adding more water
◯ cooling the mixture
◯ evaporating the water
◯ stirring the mixture

Explanation:

Stirring increases the interaction between salt particles and water molecules, speeding up dissolution. Adding more water increases total solubility but not the rate of dissolving. Cooling slows molecular motion, reducing dissolution rate. Evaporating water reduces solvent, which does not help dissolution.

Answer:

stirring the mixture
