What is the state of matter for water at 0°C?

Back

At 0°C, water can exist as both a solid (ice) and a liquid.

Front

What is the difference between a solid and a liquid?

Back

In solids, particles are closely packed and vibrate in place; in liquids, particles are close but can move past each other.
