MCQ
Water is fully filled in a container at $4\,{}^oC$, then 
  • A
    Water overflows on heating but its level falls on cooling
  • B
    Water overflows on cooling but its level falls on heating
  • Overflows on both heating and cooling
  • D
    Levels falls on both heating and cooling

Answer

Correct option: C.
Overflows on both heating and cooling
c
At $4^{\circ} \mathrm{C},$ density is maximum hence volume is minimum. Therefore it overflows on both cooling and heating.
