Help!!!! Salt...&...Water??/?

Question

Hi im trying to conduct a scince expirement and i was wondering, why does salt dissolve faster in hot water than in cold? Your answers will be highly appreciated and i hope to find out soon!!

Answer 1

hot water has a lower density than cold water, so it is able to accomodate more salt molecules (NaCl) between water atoms.
This is why it dissolves faster.

Answer 2

It is basically because the water molecules are moving around faster in the warm water compared with the cold water. In order for salt to dissolve, the water molecules have to surround and pull each ion off of the crystal. That will occur more rapidly when the molecules are moving faster.

Answer 3

Salt water dissolves faster in hot water than it does in cold water because the hot water molecules move faster than the cold water molecules. By the molecules from the salt and the hot water running into each other, it causes the salt to dissolve faster. It would also dissolve in the cold water but at a slower rate.
