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.
What else can I help you with?
Is a puddle of water evaporating on a hot day a physical change?
Evaporation is a physical change.
Water evaporating from a puddle is a example of a?
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.
Is a puddle drying up in the sun a chemical or physical change?
It is a physical change, because it is still H20 when it evaporates and turns into vapor.
Is a car driving over a puddle a chemical or physical reaction?
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.
Is a puddle of dirt a chemical change?
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.
Is a puddle of water evaporating on a hot day a physical change?
Evaporation is a physical change.
Is water evaporating from a puddle a chemical change?
Evaporation of a pudle is a physical change,
Water evaporating from a puddle is a example of a?
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.
When a cube of ice melts to form a puddle of water a chemical or physical change?
It is a physical change.
Is a puddle drying up in the sun a chemical or physical change?

Is a puddle freezing into ice on acold night a physical change or chemical 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.
Is a puddle of dirt a chemical change?
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.
What change of state occur when a puddle disappears?
The change of state that occurs when a puddle disappears is evaporation. The liquid water in the puddle turns into water vapor and escapes into the air.
Is an example of a chemical change a. ice melting c. pounding gold into a coin b. milk souring d. a puddle of water evaporating?
An example of a chemical change is b. milk souring. This process involves a chemical reaction where bacteria convert lactose in the milk into lactic acid, resulting in a change in the milk's composition and properties. In contrast, ice melting, pounding gold, and water evaporating are all physical changes, as they do not alter the chemical structure of the substances involved.
Is dirt added to a puddle a physical change?
Yes, adding dirt to a puddle is a physical change. The dirt mixes with the water, but the chemical composition of both the dirt and the water remains unchanged. This process alters the appearance and texture of the puddle, but it does not create a new substance.
When a cube of ice melts to form a puddle of water is it a physical or chemical change?
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.
