• A Chemicial change because even though it hasn't completely turned to ice it still changed bonds

• Its a Chemical change because the atoms and bonds in the water slow down

• Its a Physical and a chemical change because some parts are still water but there are still ice particles.

• Its a Physical change because the water dose not actually change form
