A) heated above\[4{}^\circ C\]
B) cooled below\[4{}^\circ C\]
C) both heated and cooled above and below \[4{}^\circ C\]respectively
D) none of the above
Correct Answer: C
Solution :
At\[4{}^\circ C\]density of water is maximum. So, if water is heated or cooled above and below \[4{}^\circ C,\] then it density will decrease, so the volume will increase, hence, water will over flow.
