Freezing is a physical change.
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
No, it is only a physical change since the chemical properties of alcohol do not change.
no as it can be turned back to water or be freeze to ice by over cooling.
Physical change: breaking a rock changes its physical appearance without altering its chemical composition. Freezing water involves a physical change where the water molecules rearrange to form a solid structure, without any change in the chemical composition of water.
No, ice crystals forming on a window is a physical change. A physical change involves a change in the form of a substance without changing its chemical composition. The water molecules in the air condense and freeze on the window, but they are still water molecules.
No, the drying of wet hair is a physical change, not a chemical change. The change in state from wet to dry is due to the evaporation of water and does not involve any chemical reactions altering the composition of the hair.
The chemical reaction of water with sodium is a chemical change.
you have to freeze it.
you freeze it
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
Freezing water is a physical change because the molecules stay the same, only changing from a liquid to a solid state. Chemical changes involve the rearrangement of atoms or molecules to form new substances.
