Physical. changes of state (solid, liquid, gas) are physical changes.
Physical
Dissolving in water is a physical change.
With a physical reaction, some of the substance changes, but the stubstance is still the same. A chemical reaction on the other hand, is hard to reverse. Physical: freezing of water, drying of clothes, mixing of iorn nails and sand Chemical: cooking of food
Chemical
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
Physical
Ocean water is a substance, not a physical or chemical change.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Physical
Boiling water is a physical change because it does not change the chemical composition of the water.
physical
physical
It is both physical and chemical. Evaporation of water is a physical process, and reduction of water from clothing is also a chemical process.
physical
Physical, as it remains water.
Solubility is a physical property of water because when water dissolves a substance, the chemical composition of the water does not change.
