Question

Maneka added a teaspoon of sugar each in two glasses of water. She stirred one of the

glasses and kept the other glass still. What do you think happened in the other glass after

twenty minutes. Explain why? Write your observations.​

Answer 1

Answer:

Stirring, or agitation helps to disperse the particles of sugar throughout the water, which is another way of increasing the surface area of the sugar and accelerating the time it takes to dissolve. The stirring motion also increases kinetic energy, which increases the temperature of the solution – and that's the next way to make sugar dissolve more quickly. An increase in the kinetic energy of the constituent particle increases the rate of interaction as well as the temperature of the solution.
