Can gases, liquids, and solids contaminate air?

Gases, liquids, and solids can indeed contaminate air, making the assertion true. This is due to the fact that air can be affected by various forms of pollution that originate from these different states of matter. For instance, gases such as volatile organic compounds (VOCs) and carbon monoxide can be released into the atmosphere from industrial processes or vehicle emissions. Liquids, particularly hazardous chemicals or waste, can evaporate and form vapors, which contaminate the air as well. Additionally, solid particulates from dust, smoke, and aerosols can become airborne and contribute to air pollution. Thus, all three states of matter—gases, liquids, and solids—are capable of impacting air quality and pose potential health risks to humans and the environment.
