The dissolution of paint from a wall by acid rain is a chemical change. This occurs because the acidic components of the rain react with the chemicals in the paint, breaking down its molecular structure and altering its composition. As a result, the paint may lose its color and adhesion, demonstrating a permanent change in the material.
Physical
First off, its spelled "breaking". No, Its a physical change, because the pencil hasn't changed its chemical components, all you did was ruin a pencil. :)
No, the odor of paint thinner is a chemical change because it involves the molecules of the paint thinner reacting with the air, producing volatile organic compounds that create the smell.
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.
No, the paint color on a new car is not a chemical property. It is a physical property because it can be observed without changing the chemical composition of the paint. Chemical properties relate to how a substance interacts with other substances to form new substances.
The process of acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the chemical components of the paint, causing a permanent change in its chemical structure.
Physical
Paint peeling is a physical change because it involves a change in the physical appearance or state of the paint without altering its chemical composition.
Chemical broooooooooooooooo niga
Yes, acid rain dissolving paint off a wall is a chemical change. This is because the acid in the rain reacts with the molecules in the paint, causing a chemical reaction that breaks down the paint's structure and changes its composition.
no. in order for a chemical change to take place the chemical make up of the paint would need to change, such as a color change. when you peel paint off a door you arent changing its chemical state.
Physical change of the paint, not the door.
Both, strangely enough. Applying the paint to the car is a physical change. The paint is a polyurethane compound. When you get it, it's in at least two containers - the paint, and a hardener. Stir them together and they undergo a chemical change.
No, because the paint simply sits on the surface of the wood, and there is no change to the molecules in the wood. Therefor, it is a physical change, until its dries then its a chemical change.
yea its a physical change cause i said so
Spray painting a car involves a chemical change because the paint chemicals react to form a new substance that bonds to the surface of the car's body. This is different from a physical change, where the paint would simply be a new layer on top of the car without a chemical reaction occurring.
The mixing of red paint and yellow paint should yield orange so your pigments must be undergoing a chemical change (the molecule is breaking down and reforming)
