As a gas, air can be compressed, that is, the molecules can be moved closer together. If no force compresses the air, it will expand indefinitely to fill the space available. The volume occupied by a given amount of gas varies with the temperature and pressure of the gas.

Answer 2

Answer:

Industrial Hygiene Engineering (Second Edition)

Recognition, Measurement, Evaluation and Control

It is desirable to review the characteristics of air and the properties of airborne contaminants to provide a background for the design of industrial ventilation systems. The purpose of this chapter is to undertake such a review. As a gas, air can be compressed, that is, the molecules can be moved closer together. If no force compresses the air, it will expand indefinitely to fill the space available. The volume occupied by a given amount of gas varies with the temperature and pressure of the gas. This fact yields several important
