Many everyday activities involve dissolving one substance in another. These include the following 3:cleaning oil-based paint from a paint brush using turpentinemixing salt into a pasta saucespraying hairspraymixing cordial with water

Sure, here are the explanations for each of the activities mentioned:

1. Cleaning oil-based paint from a paint brush using turpentine: Turpentine is a solvent, which means it can dissolve other substances. When you clean a paintbrush with turpentine, the oil-based paint (which is not water-soluble) dissolves in the turpentine. This allows the paint to be removed from the brush.

2. Mixing salt into a pasta sauce: When you add salt to a sauce (or any liquid), it dissolves into the liquid. This is because salt is soluble in water. The salt disperses evenly throughout the sauce, enhancing its flavor.

3. Spraying hairspray: Hairspray is a solution of long, chainlike molecules (called polymers) in a solvent (usually alcohol). When you spray it, the solvent evaporates, leaving the polymers behind to hold your hair in place. The polymers were dissolved in the solvent, which is why you can spray them out of the can.

4. Mixing cordial with water: Cordial is a concentrated syrup that is meant to be diluted with water. When you add water to the cordial, the cordial dissolves, creating a sweet, flavored drink. The cordial and water mix together evenly because the cordial is soluble in water.
