Question

When water containing sugar is stirred with a spoon, sugar is dissolved faster. Why does this happen?

• A. The spoon acts as a catalyst.
• B. On stirring, the temperature increases.
• C. Stirring increases the rate of interaction.
• D. The attraction between the molecules of sugar increases.

Answer 1

The correct option is C

Stirring increases the rate of interaction.

Stirring helps to increase the interaction between sugar molecules and water molecules, which causes sugar molecules to break away from each other. Hence they get dissolved faster.
