The medium which interact with long lived pollutant is:_____________?
Correct answer: C. Sink
- A. Source
- B. Receptor
- C. Sink
- D. All of them
Explanation
A sink is an environmental medium or reservoir that absorbs and stores pollutants, especially persistent pollutants that remain for long periods. A source releases a pollutant, while a receptor is an organism or place affected by it. Students may choose receptor because a pollutant eventually affects living organisms, but the question asks about the interacting medium or reservoir.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
