PPT-Measuring air pressure Modern Barometers

Earths gravitational force Atmospheric Pressure As the atmosphere is held down by gravity it exerts a force upon every surface pressure force per unit area At sea level the force is the weight of 1 kg of air that lies above each square centimeter of the surface around 15 lbs per in.

Mercury Barometer. Air pressure is measured with an instrument called a barometer.. A mercury barometer is a glass tube filled with mercury. .. How a Mercury Barometer Works. A numbered hollow tube sits in a container of mercury.. Air molecules are moving constantly! They bounce off everything like rubber balls! They are bouncing off your body and everything around you right now!. Each time an air molecule bounces off an object, it pushes (EXERTS FORCE) on that object. When billions of air molecules bounce off a surface, the force is spread over the area of that surface.. Defined as the force exerted on you by the weight of tiny air . particles . in . the atmosphere per unit area.. Earth’s atmospheric pressure = 14.7 pounds per square inch OR 1 kilogram per square centimeter. Fluids & Elasticity. (. Pressure in liquids, Measuring and using pressure, & Buoyancy).

Measuring atmospheric pressure at different altitudes above sea . level. How does atmospheric pressure vary?. Objective. The purpose of this activity is to study atmospheric pressure variations, as we reach higher . EARTH SURFACE. gravity. random. motion. Weight of all air molecules is propagated to surface by random motion of molecules. Random motion of molecules causes pressure to be applied in all directions.
