Question

what is the rate of dissolution? options: how cold a substance is, how many particles are in a substance, how quickly a substance dissolves, the color of the substance. image: solute, solvent and solution (salt, water, salt water)

Explanation:

The rate of dissolution refers to the speed at which a solute dissolves in a solvent. The first option is about temperature (coldness), the second about particle count, the fourth about color—none relate to dissolution rate. The third option, "how quickly a substance dissolves", matches the definition of dissolution rate.

Answer:

C. how quickly a substance dissolves (assuming the orange option is labeled C; if labels differ, adjust to the option with "how quickly a substance dissolves")
