Fun with Hot water | Hindi

In everyday experience we see some things floating while other things sinking in water. Things which are lighter than water float and things which are heavier than water sink. Here we will test the density of cold water and colored hot water. Take a few drops of hot colored water and with a dropper place them in the cold water. We see that the hot water goes a little below the surface of the cold water but once again floats on the top. This means that the colored hot water is lighter than the cold water. Because the hot colored water is lighter that is why it floats on top of the cold water. After some time slowly the color water will come down. This will happen when the temperatures of hot and cold water become the same. Then the water in the glass will have the same color.
