Two beakers A and B contain normal water and hot water respectively. Mohan adds equal amount of blue copper sulphate crystals to them. Which of the following observations is correct? (a) Blue colour will spread more quickly in A. (b) Blue colour will spread more quickly in B. (c) Blue colour will take the same time in both A and B to spread. (d) Blue colour will not spread in either of the beakers.
The correct answer is (b) Blue colour will spread more quickly in B.
In hot water (B), the higher temperature increases the kinetic energy of water molecules, speeding up the diffusion of copper sulfate. This causes the blue color to spread faster compared to normal water (A).
