Question

Arjit drops of crystal of pottasium permangante into 2 beaker. A and B containing hot and cold water after keeping the beaker undisturbed for some time? What does he observe and ❓

Answer 1

Arjit will observe that in the beaker containing hot water the permanganate will show the colour much faster than beaker containing cold water. This is because hot water's particles have more kinetic energy than cold water and it is clear why, because hot water is having more temperature. The kinetic energy is related to the swift showing of the colour as more the kinetic energy means more the space between particles as they are moving faster, which creates a space between them and the colour shows faster.While it would diffuse slower in beaker containing cold water as kinetic energy of particles is low.
