No. State change is a physical reaction.
Milk is normally a liquid(a suspension of cream droplets in water), by freezing it milk changes from a liquid to a solid. This is a physical change, the substance is still milk, however it is no longer a liquid, it has changed into a solid.
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
Neither. A physical change is changing something's tangible properties, such as shape or state of matter (solid, liquid, or gas), while a chemical change is turning something into something else entirely. For example, water freezing into ice is a physical change, but cake batter turning into cake is a chemical change. So, if it's the same thing that you start with as a liquid or gas and it simply becomes a solid, it's a physical change. If it becomes something else entirely, it's a chemical change. I hope that helped.
It is changing from a solid to a liquid, which is a physical change.
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
Yes. Changing from a solid to a liquid is a physical change.
Milk is normally a liquid(a suspension of cream droplets in water), by freezing it milk changes from a liquid to a solid. This is a physical change, the substance is still milk, however it is no longer a liquid, it has changed into a solid.
The physical properties of water will change when it freezes, turning from a liquid to a solid.
Physical change, because the water is only changing state, from a gas to a liquid.
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
Its a physical changed also know as condensation.
Water can exist in three physical states: solid (ice), liquid (water), and gas (water vapor). It can undergo physical changes such as freezing (turning into ice), melting (turning into water), evaporation (turning into water vapor), condensation (turning back into liquid), and sublimation (directly turning from solid to gas).
The process of LPG turning from liquid to gas is a physical change, not a chemical change. It involves a change in state, from liquid to gas, without any alteration in the chemical composition of the LPG molecules.
The change of a liquid to a gas is a physical change because its chemical properties do not change. Molecules of the liquid are just moving farther apart, therefore turning into a gaseous state.
Sure, change from solid to liquid is a physical change
