Question

When sugar is stirred with a spoon in a glass of water, more sugar is dissolved and faster. Why?

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

Answer 1

The correct option is C Stirring increases the rate of interaction

When sugar is stirred with a spoon in a glass of water, more sugar is dissolved and faster because stirring increases the rate of interaction between the molecules of water and sugar due to their increased kinetic energy.
