Novare Physical Science Chapter 9

Let's get physical...properties

100

The property of many metals that allows them to be hammered into sheets without breaking

Malleability

200

Property of some metals that allows them to be formed into a wire

Ductility

300

Many metals that have good electrical conductivity will also have this type of conductivity

Thermal

400

The temperature at which a substance changes from a solid to a liquid or a liquid to a solid

Melting point

500

This is a measure of how much matter is packed into a given amount of space

Density

Brrr...it's temperature

100

This is the melting point of water in ^oC

0 ^oC

200

This is the temperature at which all atomic motion would cease

Absolute 0 (0 K)

300

This is the term that describes the way substances behave when they are heated

Thermal Properties

400

The temperature of a substance is related to this

Its internal energy

500

This is thought to account for the temperature in outer space being 2.7 K instead of 0 K. 

Cosmic microwave background

Under Pressure and Volume

100

Pressure is a result of this

Molecular collisions

200

When a difference in pressure exists, a fluid will flow in this direction

From high pressure to low pressure

300

These phases of matter are considered incompressible

Solids and liquids

400

At a given temperature, when the pressure on a gas increases, this happens to the volume

It decreases

500

The SI system unit of pressure

Pascal

Phase the Facts

100

This phase has a definite shape and volume

Solid

200

This phase has a definite volume but no definite shape

Liquid

300

These are the four phases of matter

Solid, liquid, gas, plasma

400

This is the term used to describe the amount of energy required to change a substance from a solid to a liquid at its melting point without changing its temperature

Heat of fusion

500

This is the term used to describe the amount of energy required to change a substance from a liquid to a vapor at its melting point without changing its temperature

Heat of vaporization

The Rest of Chapter

100

This is a combustion reaction that usually involves oxygen and a fuel 

Fire

200

Most metals will undergo this reaction with oxygen in the air

Oxidation

300

This is the equation for density

D=m/v

400

This is the mathematical relationship between density and mass

Directly proportional

500

This is the mathematical relationship between density and volume

Inversely proportional
