environmental scientists collect air samples so they can test the quality of the air, they start with rigid metal containers that are completely empty the air has been pumped out of them what happens to the pressure inside the container and the volume of the container as air enters it?

Here's this. Let me know if that helps :)

Explanation:

The sampling procedures must be designed so that samples of the actual dust concentrations are collected accurately and consistently and reflect the concentrations of dust at the place and time of sampling. Sufficient number of 6-hour area samples in each distinct work area of the plant should be collected at locations which provide representative samples of air to which the worker is exposed. In order to avoid filter overloading, sampling time may be shortened when sampling in dusty areas. Samples in each work area should be gathered simultaneously or sequentially during a normal operating period. The daily time-weighted average (TWA) exposure of each worker can then be determined by using the following formula:
