Removal of inside air and supply of fresh outside air in a closed room

1.	Removal of inside air and supply of fresh outside air in a closed room is known as _________(a) Ventilation(b) Absorption(c) Adsorption(d) TransmissionI had been asked this question in my homework.The origin of the question is Functional Requirements of Ventilation System topic in section Acoustics and Ventilation of Construction & Building Materials
Answer» CORRECT answer is (a) Ventilation The BEST explanation: Removal of inside air and supply of fresh outside air in a closed room is KNOWN as ventilation. It is necessary for the creation of air MOVEMENT and for preventing suffocation conditions in big rooms. It is also important in order to prevent the ACCUMULATION of dust particles.
