When paint dries is it considered an exothermic 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.
Classify the following as a chemical and physical changes 1cooking of food 2.freezing of water 3.drying of clothes 4.mixing of iron nails and sand?
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
Is drying a hydrate a physical or chemical process?
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.
Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Is freeze drying a physical change or chemical?
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
Is the drying of wet laundry a chemical reaction?
No, it is a physical process - water evaporation.
When paint dries is it considered an exothermic 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.
Is drying cloths is chemical change?
It is a Physical Change because i dont know but im sure that is a physical change :P
Is drying hair a chemical or physical?
The drying itself is (always) a physical change.
When clothes are drying is it an endothermic or an exothermic reaction?
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.
Is drying of fish is a chemical change?
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.
Is drying fish physical change?
Drying (involving only the water evaporation) is a physical change.
Is painting a door a chemical 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.
Is freeze-drying a chemical or physical change?
yes
What is the chemical change of drying clothes?
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.
Does drying wood in a shed result in chemical change?
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.
Is drying water chemical change or physical change?
Physical, it is still H2O
