Question

Three ice cubes are placed into three equal beakers filled with water. One ice cube has a mass of $50g$, the second ice cube has a mass of $75g$, and the third ice cube has a mass of $100g$. After the ice cubes are added, each beaker is filled to the brim with water at a temperature of $1^{\circ }C$. After a period of time passes and all three ice cubes melt, which of the following situations is most likely?

• A. All three beakers have overlfowed
• B. None of the beakers have overflowed
• C. The beaker with the $100g$ ice cube have overflowed
• D. The beaker with the $100g$ and the $75g$ ice cube in them have overflowed
• E. The beaker with the $50g$ ice cube has overflowed

Answer 1

The correct option is B None of the beakers have overflowed

When ice melts , its density increases and becomes maximum at $4^{o}C$ , this is due to abnormal behaviour of water.

Now , we have $density=mass/volume$

as density of ice is increasing due to melting therefore its volume decreases that's why none of the beaker will overflow.
