You put two ice cubes in a glass and fill the glass to the rim with water. As the ice melts, the water level remains the same.

Answer: Option D

<u>Explanation:</u>

As the ice is already in the water, and that has melted, there is no addition of volume into the glass. The water spills out if extra volume is added to the container. Hence, as there is no more volume added, there should be no change seen in the level of water.

The water level stays the same. This is because either it is a solid or liquid, the volume remains same. The volume of ice before melting is same as the volume of water, when melted into.
