1. What is the primary purpose of a cleanroom?
To increase air pressure without controlling contamination sources
To reduce airborne particles and molecular contamination by controlling environmental conditions
To remove only visible dust from equipment surfaces
To maintain room temperature while allowing uncontrolled airflow
To reduce airborne particles and molecular contamination by controlling environmental conditions
Explication
A cleanroom reduces airborne particles and molecular contamination from the atmosphere, personnel, equipment, and processes through controlled filtration, airflow, pressure, temperature, and humidity.
