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 a puddle evaporating a reversible or irreversible change?
Yes, evaporation is the changing of matter from a liquid to a gas. You can reverse this process through condensation which is the change from a gas to a liquid.
Is water evaporating from a lake a physical or chemical change?
Evaporation of water from a lake is a physicalchange.They are still water molecules whether in the state of liquid, solid or gas. There has been no chemical change.
Is evaporating of water in a lake a chemical or physical change?
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.
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 water evaporating from a puddle a physical or chemical change?
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.
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.
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 a puddle of water evaporating on a hot day a physical change?
Evaporation is a physical change.
Water evaporating from a puddle is an example of a?
It is a simple evaporation.
Is water evaporating a chemical change?
Water evaporating is only a physical, not a chemical change because the water can be brought back easily to its original state where as burning a match is a chemical change.
How is evaporating water a chemical change?
Evaporation is a physical process.
Is evaporating sea water a physical chemical or nuclear change?
Evaporating seawater is a physical change. Physical changes affect the form, but not the chemical makeup of a substance. The sea water is undergoing a change in states of matter, not a chemical reaction. You can undo the change by condensing the evaporated water .
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 a puddle evaporating reversible?
Yes, the process of a puddle evaporating is reversible. When water evaporates from a puddle, it turns into water vapor, which can later condense back into liquid form through a process called condensation when the conditions are right, such as cooling temperatures.
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 water evaporating off the counter a physical or chemical change?
Evaporation is a physical change.
