The Learning Goal for this assignment is:<br />

The students will learn what are the factors that determine and characteristics<br />

that distinguish gases liquids and solids and how substances change from one<br />

state to another.<br />

Take note over the following chapter. Use the Headings provided to organize your notes. Define and number all highlighted vocabulary (total 23 ) as well<br />

as summarize the sections. You may add pictures where needed. The pictures should be an appropriate size. Use Arial 12 for all text. This document<br />

should be 3 pages and should be saved as a pdf before you submit it into Angel.<br />

13.1 The Nature of Gases<br />

Chapter 13 States of Matter<br />

Pages 420 - 439<br />

Kinetic Theory and a Model for Gases<br />

Kinetic energy 1 - is the energy an object has because of its motion.<br />

Kinetic theory 2 - is the theory that all matter consists of tiny particles that are in constant motion.<br />

-Three assumptions of the kinetic theory as it applies to gasses<br />

1. The particles in a gas are considered to be small, hard spheres with an insignificant volume.<br />

2. The motion of the particles in a gas is rapid, constant, and random.<br />

3. All collisions between particles in a gas are perfectly elastic.<br />

-During an elastic collision kinetic energy is transferred without loss of particles and the kinetic energy<br />

remains constant.<br />

-The reason gases don’t have a definite shape comes from the constant moving particles.<br />

Gas Pressure<br />

Gas pressure 3 - Results from the force exerted by a gas per unit surface area of an object.<br />

Vaccum 4 - Empty space with no pressure or no particles.<br />

Atmospheric Pressure 5 - The amount of collisions of atoms and molecules in the air.<br />

Barometer 6 - Device that is used to measure atmospheric pressure.<br />

Pascal(Pa) 7 - The SI unit of pressure which represents very small amounts of<br />

pressure.<br />

Standard Atmosphere 8 - The amount of pressure required to support 760 mm of<br />

mercury in a mercury barometer at 25 C.<br />

Numerical Relationship:1 tam = 760mm Hg= 101.3 KPa<br />

-Moving bodies exerts this type of force when they collide with other bodies.<br />

-The particles are moving bodies in a gas, but only exert small forces among<br />

collisions.<br />

-Kinetic theory can help explain gas theory because gas pressure is the result of<br />

billions of rapidly moving particles in a gas simultaneously colliding with an object.<br />

Kinetic Energy and Temperature<br />

-Particles absorb energy upon being heated.<br />

-When the energy is being stored within the particle this is known as potential energy.<br />

-the increase of kinetic energy results in an increase of temperature.<br />

For Example- When boiling a pot of water, the kinetic energy will increase as the energy increases<br />

causing a liquid to evaporate into a gas.<br />

-average kinetic energy is a range based on the different levels of kinetic energy and the one that is<br />

most common based on temperature.<br />

-The kelvin temperature represents the relationship between the temperature and the amount of<br />

kinetic energy.<br />
