A) Heated above 4°C

B) Cooled below 4°C

C) Both heated and cooled above and below 4°C respectively

D) None of the above

Show Answer

Answer:

Correct Answer: C

Solution:

Water has maximum density at 4°C, so if the water is heated above 4°C or cooled below 4°C density decreases i.e. volume increases. In other words, it expands so it overflows in both the cases.
