Answer (1)
6. b. Soil and waterA solution is a type of mixture where the substances are completely dissolved and look like one single substance. In soil and water, the soil doesn’t completely dissolve—it stays visible and can settle at the bottom, making it a heterogeneous mixture, not a solution.7. b. SteelSteel is a solid solution made of iron (metal) and a small amount of carbon. The carbon is evenly mixed with the iron, making it a uniform solid mixture.8. a. AirAir is a mixture of gases like nitrogen, oxygen, carbon dioxide, etc. These gases are mixed together evenly, making air a gas solution.9. b. SaltSalt dissolves easily in water and forms a homogeneous solution. Other choices like oil, gasoline, and sand do not fully dissolve in water.10. c. Ice and waterIce and water do not form a solution because ice is just the solid form of water, not a different substance dissolving in another. It is a physical state change, not a mixture forming a solution.
