How does air pressure change with altitude
WebAtmospheric pressure varies with the altitude; since the air mass above a certain surface is smaller as we climb up a mountain, air pressure on mountains is usually lower than air pressure at sea level. We can obtain an expression for the atmospheric pressure as a function of elevation. WebMay 13, 2024 · The change in pressure during any process is governed by the laws of thermodynamics. Although pressure itself is a scalar quantity ... The density of the air decreases with altitude in a complex manner. The velocity of a rocket during launch is constantly increasing with altitude.

WebFeb 17, 2016 · Explanation: Atmospheric pressure is dependent on two things, water content and temperature. As temperature goes up pressure goes up. Therefore as your latitude increases the pressure drops. This drop in pressure also results in a drop in the heights of the different levels of the atmosphere.
WebSep 17, 2024 · At high altitudes, the air has a very low pressure, which affects the way we breathe. This same effect occurs when people move from sea level locations, such as New York City, to the mountains, such as Denver, CO.
