IN WHICH WATER DOES MOLECULES MOVE FASTER??

Let's see in which water does the molecules move faster-
"cold water or hot water?"

Materials:
Cold water
Hot water
Food colour 
Trasperent glasses




INSTRUCTIONS
 Pour the both samples of water in each glass.
Add two-three drops of food colouring to the samples.

Observation: You will observe that the food colour in cold water spreads slowly compared to the hot water. Hence molecules in cold water move slower than the hot water!
