Final answer:
A gauge reading 160 psi is measuring pressure. Psi is a unit of pressure indicating how much force is exerted per square inch. Pressure is critical in science and can be measured in units like mm Hg, atm, or kPa.
Step-by-step explanation:
When a gauge reads 160 psi, it is measuring pressure. This is because psi stands for pounds per square inch, which is a unit of pressure. Gauges measure the force exerted by the gas or liquid in a container across a given area. In various scientific contexts, the pressure of gases is a critical parameter often measured in different units such as millimeters of mercury (mm Hg), atmospheres (atm), or kilopascals (kPa), depending on the application. To convey an understanding of pressure in scientific terms, it is crucial to convert between these units properly and understand that pressure, not temperature, volume, or weight, is being gauged.
