it is a chemical change
It is both physical and chemical. Evaporation of water is a physical process, and reduction of water from clothing is also a chemical process.
Painting a room involves a physical change rather than a chemical change. The process of painting a room typically involves applying a layer of paint, which dries and forms a new physical layer on the surface of the wall. Chemical changes involve the rearrangement of atoms and the formation of new substances with different chemical properties, which is not the case in painting a room.
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
when the glue dries it shrinks, pulling the surface of the paper together causing the wrinkle.
When you mop the floor and the wet floor dries, the moisture evaporates, leaving behind any dirt, dust, or cleaning solution residues that were lifted during mopping. If the cleaning solution was effective, the surface should appear cleaner and fresher. However, if residue is left behind, it might create a sticky or dull finish. Properly rinsing the mop and using clean water can help minimize residue for a better finish.

Physical.
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.
physical, because it can be easily reversed
Adding cornflour to water is a physical change. The reason this process is classified as such is that it does not change the chemical identities of the substances involved, which is the criterion for a process to be considered a chemical reaction. Technically, the cornflour would slowly hydrolyze in water, which would be a chemical reaction.

Yes, the color of a stain can change as it dries due to factors such as evaporation of solvents and chemical reactions with the surface being stained.
That's complicated. The wood is simply covered up, so that's a physical difference. Application of the paint is also physical, you are just putting it somewhere else. What happens as the paint dries depends on the type of paint. Evaporation of the solvent is also physical, but as gloss paint dries chemical changes happen to produce the permanent skin.
Yes, the drying of fountain pen ink is a physical change rather than a chemical change. The ink dries through evaporation of the solvent, leaving behind the solute (pigments or dyes), which does not undergo a chemical reaction during the drying process.
Nail polish evaporation is a physical change. When nail polish dries, the solvent (usually a volatile liquid) evaporates, leaving behind the solid components that form the polish film. This process does not alter the chemical composition of the remaining substances but simply changes their state from liquid to gas.
Yes, painting nails with nail varnish is considered a physical change. This is because the process involves applying a coating that can be removed without altering the chemical structure of the nails or the varnish itself. When the nail varnish dries, it forms a solid layer, but this change is reversible, as the varnish can be removed with a solvent.
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.
