A breaker is completely filled with water at \[4{}^\circ C\]. It will overflow if

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 :

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.
