When a car drives through a puddle of water, the change that takes place in the puddle is a physical change. Of course, chemical changes will take place in the engine of the car, but that's probably not what you are asking.
Nope- physical change. It is still water, but chaged to a gas. It can be changed back to a liquid by condensing it from the air.
No, a puddle of dirt is not a chemical change; it is primarily a physical change. When dirt becomes wet, its physical state changes as it absorbs water, but the chemical composition of the dirt remains the same. Chemical changes involve the formation of new substances, which does not occur in this scenario.
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
Water evaporating from a puddle is a physical change. During evaporation, water changes from a liquid to a gas, but its chemical composition (H₂O) remains the same. This process is reversible, as the water vapor can condense back into liquid water. Therefore, it exemplifies a change in state rather than a change in chemical identity.
The melting of ice to form water is a physical change. It involves a change in state from solid to liquid, but the chemical composition of the substance remains the same.
Nope- physical change. It is still water, but chaged to a gas. It can be changed back to a liquid by condensing it from the air.
Evaporation of a puddle is a physical process, not a chemical reaction. It is an endothermic process because it requires energy input to overcome the intermolecular forces holding the liquid molecules together.

It is a physical change.
The process of a puddle freezing into ice is a physical change. This is because the molecules in the water are rearranging to form a solid state (ice) without any change in their chemical composition.
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
The melting of ice to form water is a physical change. It involves a change in state from solid to liquid, but the chemical composition of the substance remains the same.
Yes, the process of a puddle freezing into ice on a cold night is a physical change. This is because the state of matter is changing from a liquid (water) to a solid (ice) without altering the chemical composition of the substance.
Yes. No chemical change has taken place, only a physical change. It can be undone (liquid water can be re-frozen)

Water evaporating from a puddle is an example of a physical change, specifically the transformation of liquid water into water vapor. This process involves a change in state from liquid to gas without altering the chemical composition of the water molecules.
