- From the above theoretical portion, we can clearly say that the volume of water is minimum at 4°C.
- So when temperature increases from 0°C to 4°C, the volume decreases or falls.
- After that when the temperature increases from 4°C to beyond, the volume increases or rises in the beaker.
- So upon increasing temperature from 0°C to 10°C, the volume of water first falls then rises in the beaker.
- So the correct answer will be option 4.
