Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.

How do you know that a chemical change is happening in the flask?
signs of a chemical reaction occurring include: -formation of a gas (bubbles) -change in color -transfer of energy (change in temperature, giving off light) -formation of a precipitate (if a solid forms out of solution)
Is hail a physical change or chemical change?
The formation of hail is a physical change as it merely involves water going from a liquid state to a solid state.
