  Ramesh took two beakers A and B containing hot water and cold water respectively. In each beaker, he dropped a crystal of copper sulphate. He kept the beakers undisturbed. After sometime what did he observe and why?

Answer:

                  The solutions of both the beakers turned blue after some time. But the colour change was observed earlier in beaker A containing hot water as compared to beaker B containing cold water. This happened due to the faster rate of diffusion at a higher temperature.    (2)
