Question

which conclusion can be drawn from the results?

a. the lower the temperature of the water, the quicker the solute will dissolve.

b. the greater the temperature of the water, the quicker the solute will dissolve.

c. the more solute that is added to the water, the longer it will take the solute to dissolve.

d. the less solute that is added to the water, the longer it will take the solute to dissolve.

Explanation:

In general, for most solutes, as water temperature increases, the kinetic energy of molecules increases, leading to faster dissolution (so A is wrong, B is correct). For C and D, while solute amount can affect dissolution time, the typical relationship is that more solute (up to saturation) takes longer, but this is less a universal rule like temperature's effect, and the question likely focuses on temperature - related conclusion. Also, D's statement is incorrect as less solute should dissolve faster or take less time.

Answer:

B. The greater the temperature of the water, the quicker the solute will dissolve
