Question:

If you fill a glass to the brim with ice water and the ice melts, what will happen?

1) The glass will over flow as the ice turns to water

2) The level of water in the glass will remain unchanged as the ice melts.

3) The water level will drop slightly as the ice melts.

4) I'll never find out because I'll drink the water or walk away before anything happens.​

Answer:

1) The level of water in the glass will remain unchanged as the ice melts is the correct answer.

Explanation:

When a glass is filled with ice it has occupied some space in the glass and then the water is poured into it.

Water will fill the empty space left by ice in the glass which means that the ice has displaced the weight of liquid to its own weight.

Archimedes principle says that the body floating in a liquid displaces weight of liquid equal to its own weight.

As the ice will melt it will turn into water it will occupy same place as when it  was occupying at time of ice thus, water level remains unchanged.
