(II). adjacent pressure.
(III). adjacent pressure.
(IV). atmospheric pressure.
Q: Answer the following question given this paragraph: 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. Q: What type of pressure is the pressure exerted by gas particles in earth's atmosphere as those particles collide with objects? A:
A:
(IV).
