GASES OH MY!!!

Chapter 3 Sections 1-4

SOLIDS What makes a solid a

solid???

a) Has to have a definite shape

b) Has to have a definite volume

c) Has particles that are fixed and tightly packed together

d) The particles vibrate or move back and forth slowly

THE TYPES OF SOLIDS crystalline solids

examples: salt, sugar, and even snow are solids that are made up of crystals and has a regular repeating pattern

amorphous solids examples: plastics, rubber, and glass are solids that does not have a regular repeating pattern, and becomes softer and change into a new substances but does not melt

LIQUIDSWhat makes a liquid a liquid?a) Has to have a definite volume b) Has NO definite shape of its ownc) Has particles that move freely which makes

a liquid a fluid

PROPERTIES OF LIQUIDS Surface tension is the result of an inward pull among the

molecules of a liquid that brings the molecules on the surface closer together

Viscosity is a liquid’s resistance to flowing (it

depends on the size and shape of its particles and attractions between particles

GASES What makes a gas a gas?a) Has NO definite shape or volumeb) Has particles that move freely and fills the

space of a room or container that is available

c) It is also known as a fluid.

GAS BEHAVIORMEASURING GASES

Volume- The measurements used to measure the volume of an object are: centimeters (cm³), milliliters (mL), Liter (L), and other units. Formula to find volume is length x width x height.

Temperature-the measure of the average energy of random motion of the particles of a substance.

Pressure- the number of times particles hit the surface of a substance.

The formula to find the pressure of an object is: Pressure: Force/Area

BOYLE’S LAW Boyle’s Law

When a pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased the volume increases.

Boyle’s Law

pressure goes up volume goes down

pressure goes down volume goes up

CHARLES’S LAW Charles’s Law When temperature of a gas is

increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.

Temperature increases Volume increases

Temperature decreases Volume decreased

GRAPHING GAS BEHAVIOR

Graph- A diagram that tells how two variables, or factors change, and are related.

A graph consist of a y-axis and an x-axis. The y-axis is labeled by the responding variable. The x-axis is labeled by the independent variable.

GRAPHING GAS BEHAVIOR The Charles’s Law always creates a graph that is

directly proportional.

Directly proportional- a term that is used to describe the relationship between two variables whose graph is a straight line passing through the origin (0,0).

The Boyle’s Law always creates a graph that is vary inversely.

Vary inversely- a graph of two variables that forms a curve.

WORDS TO KNOWa) Solid b) Liquidc) Gasd) Pressuree) Boyle’s Lawf) Charles’s Law

GLOSSARY1. Solid- has definite shape and volume and has particles that are

packed closely together

2. Liquid- has no definite shape but has definite volume and has particles that move easily and freely which makes it a fluid

3. Gas- has no definite shape or volume and particles move freely which is also a fluid

4. Pressure-the force of a gas’s outward push divided by the area of the walls of the container

5. Boyle’s Law- pressure goes up volume goes down

pressure goes down volume goes up

6.Charles’s Law- temperature volume temperature volume
