Overview Sun light particles in the atmosphere These particles are too small to see with the human eye but we can detect the light they scatter In this demonstration we will observe how light.

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”. The Kinetic-Molecular Theory of Matter. Gases. Behavior of Atoms. Kinetic-molecular theory. .  . based on the idea that particles of matter are always in motion. Can be used to explain the properties of solids, liquids, and gases in terms of the energy of the atoms and the forces that act between them. Partial Pressure, . Gases in Chemical . Reactions . & KMT. Partial Pressures of Gases in Mixtures. Each gas, in a mixture of gases. , exerts . a specific amount of pressure. This pressure can be calculated using the ideal gas law:. 2. Gas Laws. We will examine the quantitative relationships, or . empirical laws. , governing gases. . Basically, we will learn about equations that are available to calculate P, V, T, & n for gases. .

Admonish (v.) to caution or advise against something; to scold mildly; to remind of a duty syn : warn, call on the carpet ant: praise, pat on the back Dilemma (n.) a difficult or perplexing situation or problem 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. . The particles are far apart.. The particles move very fast.. The particles have no attraction nor repulsion for each other.. The fact that they have no definite shape or volume – they take the shape of the container.. 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. A strong attraction to each other and a large volume . A strong attraction to each other and no volume . A weak attraction to each other and a large volume . A weak attraction to each other and no volume .
