Solution
The correct option is C Difference in pressure
Vacuum cleaner:
- Vacuum cleaners are electrically driven devices that eliminate and polish a variety of surfaces by collecting but also eliminating dust and tiny particles.
- The cleared dust particles and contaminants are dumped within the cleaning solution in a dust pouch.
- Utilizing electrical power, air is continually pulled out from inside a vacuum cleaner. This produces an internal vacuum. Outside air at atmospheric pressure is thereby drawn in, accompanied with light dust and dirt.
Therefore, option C is the correct choice.
