A) heated above\[{{4}^{o}}C\]
B) cooled below\[{{4}^{o}}C\]
C) both heated and cooled above and below\[{{4}^{o}}C\]respectively
D) none of the above
Correct Answer: C
Solution :
Water has maximum density at\[{{4}^{o}}C\], so if the water is heated above\[{{4}^{o}}C\]or cooled below\[{{4}^{o}}C\], density decreases ie, volume increases. In other words it expands so it overflows in both the cases.
