When ice is frozen why does it crack glass?

Answer 1

The particle theory explains how particles behave in solids, liquids, and gases. When water freezes, it expands at a rate of 9%. It can expand because the particles in water are able to move in any and all directions.

However, a glass container is made of tightly-packed, very dense particles that are very strongly attached to each other. The particles in glass cannot move like the particles in water can.

So when water is placed into a glass container and then frozen, it expands. The glass container cannot expand, and if there is no other place for the frozen water to expand to then it will break the glass that contains it.

Answer 2

The change between the liquid and solid form is called freezing (also known as solidification). The temperature inside the freezer causes the particles to freeze, and pack together, thus creating a solid form.

Answer 3

Ice is less dense than water. It takes up approx 9% more space when it is frozen than in its liquid form.
Therefore when the liquid in the bottle freezes it will break the bottle as it doesnt have enough room to expand in volume.
This is not the case with spirits as alcohol does not freeze.
It will happen with all liquids that consist of a high level of water, ie wine, champagne,carbonated drinks.

Answer 4

When ice from a cold substance comes in contact with the warmth of glass, it can cause thermal stress on the glass due to the rapid temperature change. This stress can create cracks in the glass as it expands and contracts at different rates. Using tempered glass can help minimize this issue as it is more resistant to thermal stress.

Answer 5

Water expands as it freezes, and therefore if it is in a glass container, the container may not be large enough to hold the increased volume.

Answer 6

Thermal Shock

glass breaks due to un even surface temperature.

Answer 7

Glass becomes more brittle when frozen.
