Aspoon of salt is added to water. which of these will increase how fast the salt dissolves? check all of
the boxes that apply.
adding another spoon of salt
stirring the salt and water
cooling the water
crushing the salt so the grains are smaller
adding more water

Stirring the salt and water

Crushing the salt so the grains are smaller

Explanation:

Another way that is not in the choices that would increase the rate of dissolving of a solute in the solvent is heating the solvent.  This increases the kinetic energy of the particles hence increasing collision rates. This helps increase the dissolution of the solute.

Stirring helps break down the solute to smaller particles. Smaller particles have a larger surface area to volume ration on which collision with solvent molecule can occur hence faster dissolution.  

your picture is not part of the scientific method.

i do not get it   at all
