Question

What will happen to the level of water in a heating pot if ice is added to it?

• A. Decreases
• B. Remains the same
• C. Increases
• D. Increase, and then decrease

Answer 1

The correct option is B Remains the same

The density of ice is less than that of water. That's why it floats on water.
$\text{Mass}=\text{Density}\times \text{Volume}$
Consider two cases; in the first case, an ice cube of mass m is added to some water. If it is floating, it will have to displace enough water to support its weight.
In the second case, the ice cube has melted. It turns into the volume of water that it displaced before. So, the added volume is the same as the displaced volume; hence, there will be no change in the level of water.
