Question

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

Water has maximum density at 4° C, so if the water is heated above 4° C or cooled below 4° C, density decreases volume increases. In other words it expands so it overflows in both the cases.

Q. A beaker is completely filled with water at $4^{\circ} C$ . It will overflow if

heated above $4^{\circ} C$

cooled below $4^{\circ} C$

both heated and cooled above and below $4^{\circ} C$ respectively

none of the above

Water has maximum density at $4^{\circ} C$ , so if the water is heated above $4^{\circ} C$ or cooled below $4^{\circ} C$ , density decreases volume increases. In other words it expands so it overflows in both the cases.

Q. A beaker is completely filled with water at 4∘C. It will overflow if

heated above 4∘C

cooled below 4∘C

both heated and cooled above and below 4∘C respectively
