A beaker is completely filled with water...

A beaker is completely filled with water at `4^(@)C.` It will overflow if

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

Text Solution

Verified by Experts

The correct Answer is:
C
Water has moximum density at `4^(@)C` or colled below `4^(@)C` density decreases i..e., volume increase. In other words, it expands so it overflows in both the cases.
