A. Ventilation units must be installed in a commercial building where air ventilation is not adequate enough to maintain a balance between the amount of oxygen and carbon dioxide in a building. Applying the ideal gas law, what is the use of ventilation units in the buildings? How do you relate this to the properties of the ideal gas?
Ideal gas laws are also employed in airplanes where a proper pressure balance both inside and outside must be maintained. Why is it important to maintain the proper pressure balance on both inside and outside of the airplanes?
