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.. How Long Will the Candle Burn. ?. 1. Put on your goggles.. 2. Stick a small piece of modeling clay. onto an aluminum pie pan. Push a. short candle into the clay. Carefully light. the . candle. 3. . Hold a small glass jar by the. 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”. Atmospheric layers 15 km and the Impact on Living Things. Earth’s Atmosphere. The gases that surround Earth (and other planets) make up the atmosphere. These gases are like an envelope that protects us from the radiation that is caused by the sun’s . . General Characteristics. Composition- Gases, water vapour and dust particles.

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 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.
