What Causes The Force Of Pressure? Pressure is a stress. It is a scalar given by the magnitude of the force per unit area. In a gas, it is the force per unit area exerted by the change of momentum of the molecules impinging on the surface. … It is this force, acting on the
What Does South Elevation Mean? The top drawing is labeled the south elevation, meaning the elements and surfaces that are depicted are facing south; we are looking toward the north. The same reasoning applies to the bottom drawing, which is the other side of the building on the north. What is an east elevation? What
Why Is It Cold At High Altitudes? High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other. Why does temperature decrease with higher
What Decreases As Elevation Increases? As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by “thin air.” Thin air exerts less pressure than air at a lower altitude. Does volume decrease as altitude increases? In
What Is The Relationship Between Altitude And Temperature? Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer. What is the relationship between altitude and temperature class 7? 2. Altitude:
