Final answer:
The main disadvantage of using compressed air to clean carpets is the dispersal of matter and disruption of intermolecular forces.
Step-by-step explanation:
The main disadvantage of using compressed air to clean carpets is that it can cause dispersal of matter and disruption of intermolecular forces.
When compressed air is released into the lower-pressure air of the room, it spreads out in a more uniform manner, making it difficult to target specific areas.
Additionally, the release of compressed air requires an input of energy to disrupt the forces between gas molecules, which can be inefficient.
