The absorption of water is not a chemical reaction.
No, the drying of paint is considered a physical change, not a chemical reaction. The drying involves the evaporation of the solvent in the paint, and it is not an exothermic reaction because it does not involve the release of heat.
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
Drying a hydrate is a physical process. It involves the removal of water molecules through methods such as heating or desiccation without changing the chemical composition of the compound.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
No, it is a physical process - water evaporation.
No, the drying of paint is considered a physical change, not a chemical reaction. The drying involves the evaporation of the solvent in the paint, and it is not an exothermic reaction because it does not involve the release of heat.
It is a Physical Change because i dont know but im sure that is a physical change :P
The drying itself is (always) a physical change.
The process of clothes drying is not a chemical reaction, so it is neither endothermic nor exothermic. It is a physical process where water evaporates from the fabric due to heat energy, resulting in the drying of the clothes.
No, drying of fish is a physical change, not a chemical change. The process of drying simply involves the removal of water from the fish, causing it to undergo a physical transformation, but its chemical composition remains the same.
Drying (involving only the water evaporation) is a physical change.
No, painting a door is a physical change, not a chemical change. The paint is simply adhering to the surface of the door through physical means such as drying and curing, rather than undergoing a chemical reaction to form new substances.
yes
Drying clothes involves a physical change rather than a chemical change. The water present in the wet clothes evaporates when exposed to heat or air, changing its state from liquid to gas without undergoing a chemical reaction.
Drying wood in a shed does not result in a chemical change because the process involves the removal of water through evaporation, which is a physical change. The structure and composition of the wood remain the same.
Physical, it is still H2O
