ACTIVITY 2
Drop few crystals of sugar / tang/ Glucon-D into a glass of hot water and another
containing cold water.
Do not stir the solution. Allow the crystals to settle at the bottom.
Answer the following questions:
1. Name and define the process which is taking place here.
2. Record your observation in both the glasses.
3. Does the rate of mixing change with temperature? Why and how?

Answer:
Answer
Correct option is
B
On stirring, temperature increases
C
Stirring increases the rate of interaction
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.
Hence, option (B) & (C) are correct.
