In what range of temperature is the expansion of water anomalous?

A. +208°C to +212°C

B. -800°C to -76°C

C. 0°C to 4°C

D. -40°C to 0°C

QUICK ANSWER…

C

EXPLANATION…

The volume of water is expected to start increasing immediately after the melting of ice, but this is not the case. Instead, its volume initially begins to reduce from 0 degrees celsius to 4 degrees celsius where it then picks up and starts increasing as expected. This is called anomalous expansion of water.

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is correct.
  4. D is not the correct answer.

HELPFUL TIPS…

You may please note these/this:

  • Anomalous expansion of water occurs between 0 degrees celsius to 4 degrees celsius.
