Water and icecubes

This is super simple experiment which needs only water and icecubes

A.Normal water at room temperature.

Take a glass and fill it with half of water and mark the level with sketch pens or paper tapes.Add the icecubes in to the water.

What will happen?the level of water will increase.

Our learning

When you put a thing in to water,the level of the water rises.The water level that rises is equal to the weight of the thing that you have added.

B.Warm water.

Similarly,we tried with warm water.Fill the water to almost top of the glass and make sure that water donot spill on the edge of the glass.

Gently add icecube to the warm water.

Will the water level change??.

No..Water level will not change.

Why it doesn’t change when ice cube melted in warm water?

Eventhough the icecube melted,the water doesn’t overflow.When water freezes to make ice ,it expands and takes more space.But the water from ice takes up less space than ice itself.Thus when the icecube melts,the level of the water stays about the same.
