Question

carla is making two drinks. she is making one hot chocolate and one chocolate milk. which best describes the agitation needed to make sure the cocoa powder is mixed in well?
chocolate milk would require more agitation than hot chocolate does.
hot chocolate would require more agitation than chocolate milk does.
they would both require the same agitation.
neither would require any agitation.

Explanation:

The solubility of substances is affected by temperature. Higher - temperature solvents (like hot liquid in hot chocolate) can dissolve solutes (cocoa powder) more easily. Cold milk in chocolate milk has lower solubility for cocoa powder, so more agitation is needed to mix the cocoa powder well.

Answer:

Chocolate milk would require more agitation than hot chocolate does.
