The ice expands as it freezes - which creates weak points in the rock, causing it to break apart.
At 0 degrees Celsius, water freezes and turns into ice. This is the temperature at which water changes from a liquid to a solid state.
Ice (solid) starts out as water (liquid) and when water freezes it becomes a solid.
Water turns to solid when it freezes.
No, it is physical weathering. Ice wedging occurs when water seeps into cracks in rocks and freezes. Water expands when it freezes, and when that happens it can crack the rock, causing the rock to break down over time. No chemical changes occur during this process. The water stays water, it just changes state, and the rock stays rock, it just breaks down into smaller pieces.
When liquid water freezes, it releases heat to the surroundings. This is because as water cools and freezes, it is converting its energy to a lower state, thereby releasing energy in the form of heat to the surrounding environment.

A LIQUID FREEZES TO SOLID
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
The rock cracks and weathers.
The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
Water expands when it freezes, therefore it tends to cause the rocks to crack (or perhaps I should say, it causes existing cracks to get larger, leading to the disintegration of the rock).

Water expands when it freezes. In winter, water gets into minute cracks in the rocks and then as it freezes it expands and makes the cracks bigger. So more water gets in then freezes so the cracks get bigger still until the rocks break apart.
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
