Question

1. a solution is a mixture. the part of the solution in the greater amount is called the

a solute
b solvent

1. which method would speed up the rate in which sugar would dissolve in a glass of tea?

a stir the sugar in the tea
b chill the tea first

1. the key point when trying to speed up the dissolving process is to increase the

a contact between the solvent and solute
b content unclear

Explanation:

1. For the first question: In a solution, the component present in the larger amount that dissolves the other substance is defined as the solvent, while the solute is the smaller component.
2. For the second question: Stirring increases the interaction between solute (sugar) and solvent (tea), speeding up dissolution; chilling slows molecular motion and reduces dissolution rate.
3. For the third question: Speeding up dissolution relies on increasing how much the solvent and solute interact, as this allows the solute to disperse faster in the solvent.

Answer:

1. B. solvent
2. A. stir the sugar in the tea
3. A. contact between the solvent and solute
