Q.) 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.
Answers
The water level will drop slightly as the ice melts.
Explanation:
Density of ice is less than Density of Water
Density = Mass/Volume
=> Mass = Density * Volume
Mass of Ice = Mass of Water
Density of ice * Volume of ice = Density of Water * Volume of water
=> density of ice / Density of water = Volume of Water / Volume of ice
=> Density of ice is less than Density of Water
density of ice / Density of water < 1
=> Volume of Water / Volume of ice < 1
=> Volume of Water < Volume of ice
Hence The water level will drop slightly as the ice melts.

Answer:
The water level will drop slightly as the ice melts.
Explanation:
One interesting property of water is that it achieves maximum density as a liquid, not as a solid.
So, ice is less dense than water and floats. When it melts, it becomes more dense. More mass per unit volume means the level of the liquid drops slightly.
