in layman's terms:
when the water is hot, there is more energy and the water particles are moving faster, thus there is a higher amount of collisions per unit of time with the solute particles (the thing you are dissolving)
To speed up the dissolving of a solute you can, among many options:Heat up the mixtureStir the mixtureAdd more solute, then filter off the excessCrush the solute to give it a greater surface area

Na+, Br-
they break up because the salt in it is dissolving gradually
The molarity of a solution made by dissolving 23,4 g of sodium sulphate in enough water to make up a 125 mL solution is 1,318.
When preparing juice from a frozen concentrate, the process of dissolving can be sped up. Adding hot water ad stirring are both ways to speed up the process.

You can either add more boiling hot water or stir it to make the granules dissolve easier!
The heat gives the water molecules more kinetic energy to pull the alka seltzer particles apart (dissolve) , hence the increased temperature would speed up the rate of reaction.
1. You can stir it 2. You can heat it up so it boils 3. You can crush the material you are dissolving.
At lower temperature the solubility decrease.
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
Heating, grinding, stirring are physical processes.
As a rule, solids (like a Vitamin C tablet) dissolve faster in hot water than cold water. As you raise the temperature, the fugacity of the solid increases thus increasing the driving force for dissolving.
