What really matters ?

Presented By: Jeena Williams and Shavonte Harris

States of matter

Solids – a solid has a definite shape and a volume.

Liquid- has a definite volume but no shape of it’s own.

Gas- a state of matter with no definite shape or volume

Solids

solids here are two types of solids:

~crystalline solids-solids that are made up solids

~amorphous-a solids made up of particles that are not arranged in a pattern

liquids

The particles in a liquids are:

~fluid- “s substance that flows”

Properties of a liquid: surface tension- is the result of an inward pull.viscosity- a resistance to flowing

Gas

A characteristics of gas is:

As they move, gas particles spread apart, filling all the space available. Thus, a gas has neither definite shape nor definite

Change of state

Melting-the change in state from a solid to a liquid.Freezing-the change of state from liquid to solid.Boiling-another kind of vaporization.

Solid to a liquid

When a solid change to a liquid it is melting, for example when an ice cream which is a solid melts .

Solid to a liquid

When a solid changes to a liquid it is freezing, for example when water turns into ice.

Liquid to a gas

When a liquid changes to a gas, it is also called vaporization. For example, mirror fog up in the bathroom

Section 3 Gas BehaviorPressure- The force exerted on the surface divided by the total area over which the force is exerted. Boyle’s Law- This relationship between the pressure and the volume of a gas.Charles’s Law- This principle

Measuring Gases

How do you measure gases? Well the answer is it’s when working with a gas, it is helpful to know its volume, temperature, and pressure.

Pressure and volume

Boyle’s Law- is when the pressure and volume is measured for increasing and decreasing volume and pressure.

Pressure and Temperature

Increasing temperature raised temperature is when temperature of a gas at constant volume is increased, the pressure of the gas increases.

Volume and Temperature

Charles’s law- was found when the temperature of a gas in increased at constant pressure, it’s volume increases. When the temperature of a gas is decreased at constant pressure volume decreases.

Section 4 Graphing gas behavior

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

Temperature and volume

Directly proportional-when a graph of two variables is straight line passing through, the variables.

When a graph of two variables are said to vary inversely with one another.
