Meteorology is the study of the changes in temperature, air pressure, moisture, and wind direction in the troposphere. It is basically the science of the atmosphere. It gives us the basic idea of the forces that cause weather and climate. As well as how human activities can affect climate, for example pollutants in the atmosphere. He/she uses scientific principles to explain, understand, observe or forecast the earth's atmospheric phenomena.. Chemistry—2. nd. semester. Properties. All gases share some physical properties:. Pressure (P). Volume (V). Temperature (T). Number of moles (n). These properties combine to describe the behavior of gases using the “gas laws”. Earth’s . protective bubble.

Each gas, in a mixture of gases. , exerts . a specific amount of pressure. This pressure can be calculated using the ideal gas law:. Gases Kinetic Molecular Theory and Gas Laws Learning Objectives Be able to explain behavior of Gases using Kinetic Molecular Theory Explain relationship of volume, temperature, and pressure Use absolute temperature scale Behavior of Gases Chapter 3.2 Behavior of Gases What behaviors do gases display? Do they behave the same all the time? What variables are involved with gas behavior? Variables Pressure – the amount of collisions between gas particles and walls of the container (balloon). Measured in kilopascals ( Particle Theory. All . matter consists of many, very small particles . The particles . are constantly moving or in a continual state of motion. . The . degree to which the particles move is determined by the amount of energy they have and their relationship to other particles. . Kinetic Molecular Theory of Gases. This is the six point model that is used to explain the behavior of gases. Points of the Kinetic Molecular Theory. 1. Gases are composed of atoms or molecules that have mass. Proportions of gases in the atmosphere. Composition and evolution of the atmosphere. Combustion of fuels. Source of atmospheric pollutants.. Most fuels may also contain some . sulfur. .. Gases from burning fuels. 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.
