Question

Give a reason for the following.

Ice floats on water.

Short Note

Solution

Reason:

  1. This is because ice is lighter than water.
  2. It means that the density of ice is lower than that of water.
  3. Since ice is a bad conductor of heat it does not allow heat to pass through it.
  4. So, the water below the ice remains in liquid form, where most of the aquatic life lives.
