in the salt water solution , the solvent is water & in the salt water solution , the solvent is water0 ->  if the water in the salt water solution evaporates, then the solute of the solution will remain  if something is in the sunlight then that something will absorb solar energy & salt water is placed in sunlight for a day ->  the salt water will absorb solar energy  the salt water will absorb solar energy & in the salt water solution, the solvent is water ->  the water in the salt water solution will absorb solar energy  the water in the salt water solution will absorb solar energy & if a substance absorbs solar energy then that substance will increase in temperature ->  the water in the salt water solution will increase in temperature  the water in the salt water solution will increase in temperature & temperature is a measure of heat energy ->  the water in the salt water solution will increase in heat energy  the water in the salt water solution will increase in heat energy & evaporation means a substance changes from a liquid into a gas by increasing heat energy & water is a kind of substance ->  the water in the salt water solution will evaporate  if the water in the salt water solution evaporates, then the solute of the solution will remain & the water in the salt water solution will evaporate ->  the solute of the salt water will remain after water evaporates  the solute of the salt water will remain after water evaporates & in the salt water solution , the solute is salt -> the salt in the salt water will remain after the water evaporates
