Question

Which factors can affect the amount of cocoa mix that can be dissolved in water? Check all that apply.

adding ice

adding heat

altering amount of water

using a different kind of cocoa mix

stirring

breaking down the cocoa mix into smaller particles

Answer 1

Apply: adding ice; adding heat; altering amount of water; using a different kind of cocoa mix.

Reasoning:
- Adding heat (higher temperature) generally increases the solubility of solid mixes in water.
- Adding ice lowers temperature (and until it melts) and so can reduce how much will dissolve.
- More water lets you dissolve more total cocoa (solubility is expressed per volume of solvent).
- Different mixes have different ingredients and solubilities.

Do not apply: stirring; breaking the mix into smaller particles — these speed up how fast the mix dissolves but do not change the maximum amount that will dissolve at a given temperature and solvent amount.
