Air pressure decreases with increasing height above the surface because the weight of the air above a given point decreases as altitude increases. At higher elevations, there is less air mass above exerting downward force, leading to lower pressure. Additionally, the density of air decreases with height, meaning fewer air molecules are present to exert pressure. This relationship is a fundamental principle of atmospheric physics.
What else can I help you with?
Weather element that always decreases with increasing height?
Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.
How can the speed of a chemical reaction be increased?
The rate of chemical reaction can be increased by following ways:- 1. Adding a catalyst. 2. Increasing the temperature of system. 3. Increasing the surface area. 4. Increasing the stirring/mixing rate 5. Increasing the pressure of system (but take care as this is not always the case)
Is a pressure switch tagged PSL 1234 set to trip on increasing or decreasing pressure?
A pressure switch tagged PSL 1234 is typically set to trip on increasing pressure if it is designed to activate when the pressure exceeds a certain threshold. Conversely, if it is intended to activate when the pressure drops below a specified level, it would trip on decreasing pressure. The specific function would depend on the application and configuration of the switch. Always refer to the manufacturer's documentation for the exact operation of a particular pressure switch.
As the density of air decreases its pressure what?
Temperature is always measured when surface have transition from hot to cold or vice-versa. When molecules decrease in density, implies the individual molecules get cooler/hotter faster to room temp.hence,When air molecules decrease air temperature rapidly changes to room temperature or ambient temperature.
What are some ways by which plants can increase their rates of photosynthesis and transpiration?
Increasing the temperature of the reaction will always increase the rate, though the actual yield will depend on whether the reaction is exothermic or endothermic. Increasing the pressure of the... Read More
Under which conditions will the volume of a given sample of a gas always decrease?
The Ideal Gas Law states that PV=nRT, where P=pressure, V=volume, n=number of moles of gas, R=the relativity constant, and T=temp in Kelvin. According to this law, volume (V) varies as V=(nRT)/P. Using this, we can determine that the volume would normally increase with an increase in the number of moles and/or an increase in the temperature and/or a decrease in pressure. Therefore, we can logically determine that the volume of a gas would decrease in the instance of increasing temperature if either the number of moles of gas was decreased or the pressure was increased (to an extent where the level of volume increase by temperature change has been overcome.)
Is The pressure exerted on an object by a fluid always parallel to the surface of the object?
No, the pressure exerted on an object by a fluid is always perpendicular to the surface of the object. This is due to Pascal's principle, which states that the pressure in a fluid is transmitted equally in all directions.
What would increase the reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
What explains why a balloon bulges on one end when you pinch the other end?
The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.
Does are come together or move apart in an area of surface low pressure?
Air always flows towards areas of low pressure - and away from high pressure.
Weather element that always decreases with increasing height?
Pressure always decreases with height. This is because atmospheric pressure is just a measure of how much air is weighing down. So the higher you go in the atmosphere, the less air is above you (more of it is below you) and the lower the pressure will be.

Does the pressure of a gas always increases with increasing temperature?
In general, the pressure of a gas increases with increasing temperature, assuming volume remains constant (according to Gay-Lussac's Law). This is because as temperature increases, gas molecules gain more kinetic energy and collide with the container walls more frequently and with greater force, resulting in increased pressure.
List two properties of the pressure exerted on an object by a fluid?
The pressure increases as the object goes deeper into the fluid; the pressure is always perpendicular to the surface of the object
How does air pressure always decrease with altitude?
As altitude increases, the air pressure decreases because there are fewer air molecules above pushing down on the air below. This results in lower air pressure at higher altitudes.
Is the entropy of the universe increasing?
Yes, the entropy of the universe is increasing over time, according to the second law of thermodynamics. This law states that in any isolated system, the total entropy, or disorder, will always increase or remain constant, but never decrease.
