Answer 2

The given graph represents the following.

• a) The graph represents the process of anomalous expansion of water. This is an abnormal property of water where it abruptly begins expanding when cooled to a temperature below 4⁰C.
• This is why ice floats on water and the surface freezes first in winter. Its volume increases but density is lesser than that of the liquid.
• Water at the coldest temperature is the lightest while that at 4⁰C and above is heavier.
