Q: What type of pressure is the pressure exerted by gas particles in earth’s atmosphere as those particles collide with objects?


Read this paragraph and choose the correct option from the provided answers:

Atmospheric pressure is the pressure exerted by gas particles in Earth’s atmosphere as those particles collide with objects. A barometer is an instrument used to measure atmospheric pressure. A traditional mercury barometer consists of an evacuated tube immersed in a container of mercury. Air molecules push down on the surface of the mercury. Because the inside of the tube is a vacuum, the mercury rises inside the tube. The height to which the mercury rises is dependent on the external air pressure.

 Choices:

- vertical pressure

- adjacent pressure

- adjacent pressure

- atmospheric pressure


A:
atmospheric pressure
