Which would allow you to add more powdered mix to the water?

Heating the water generally increases the solubility of a solid powdered mix, so more of it can dissolve in the same amount of water. This makes “Heat up the water first because it increases solubility of the powdered mix” the correct choice. Stirring can help the mix dissolve faster, but it does not explain why more mix can dissolve overall.
