PROPERTIES OF MATTER

by Tc Waniepaed

What is Matter?

• Anything made of particles. 

• It has mass and volume (takes up space).

• Matter can be in the form of a solid, liquid, or gas.

Multiple Choice

What is matter?

• Everything

• Nothing

• Nothing you can see

• Just liquids

Physical Properties

• Can be observed with one or more of your 5 senses.

• Can be observed without changing what the object is made of.

Multiple Choice

Physical Properties

• Can't be observed unless you change what they are made of.

• Can only be observed under a microscope

• Can only be done in science.

• describe the appearance of something.

Mass

• A measure of the quantity of matter in a body

• The SI unit for mass is kilogram (kg)

• What is the instrument used to measure mass?

Volume

• The amount of space an object occupied

• The SI unit for volume is cubic meter (m³)

• There are 3 different ways to measure volume :

• 1. Volume of liquid

• 1. Volume of regular solid

• 1. Volume of irregular solid

Multiple Choice

What does volume measure?

• mass

• the size of object

• how much space object takes up.

• the speed something goes

Density

• The quantity of matter packed into a unit volume

• The SI unit of density is kg/m³

• Formula of density, Density = mass/volume

• By comparing the densities of substances, we can predict whether one will float in other

Flexibility

• The ability of a material to bend without breaking

• It return to its original size & shape after bending

Hardness

• The hardness of a material is its ability to withstand scratches

• A material can cut or scratch a material less hard than itself

Melting Point

• The temperature at which it changes in state from solid to liquid

Boiling Point

• The temperature at which it changes in state from a liquid to a gas

Strength

• The ability of material to support a heavy load without breaking or tearing

Electrical Conductivity

• A measure of how readily electricity passes through it

• Electrical Conductors : Materials that allow electricity to pass through them easily.

• Electrical Insulators : Materials that do not allow electricity to pass through them easily.

Thermal Conductivity

• A measure of how readily heat passes through a material

• Heat Conductors : Materials that allow heat to pass through them easily.

• Heat Insulators : Materials that do not allow electricity to pass through them easily.

Multiple Choice

Bridges need to withstand the weight of the cars crossing it. Steel which made up of iron and carbon, is ussually used in constructing bridges.

Pure iron is too soft to be used in constructing bridges.

Which of the following can be inferred from the information above?

• Adding carbon to iron makes iron harder & stronger

• Steel & pure iron are good electrical conductors

• Steel & pure iron are good heat conductors

• Pure iron is softer but stronger than steel

Multiple Choice

If matter sinks in water it is

• less dense.

• buoyant.

• least dense.

• more dense.

Multiple Choice

What is the volume of the rock? The water level is displaced from 20 mL to 23 mL with the rock.

• 3 mL

• 23 mL

• 20 mL

• 43 mL

Multiple Choice

Which state of matter has a fixed shape and volume and it's molecules move very slowly?

• Liquid

• Gas

• Solid

• Plasma

Multiple Choice

Anything that has mass and takes up space is called

• volume

• matter

• magnetism

• electricity

Multiple Choice

What are the three states of matter?

• gas, liquid, mass

• solid, liquid, gas

• mass, volume, thermal energy

• gas, temperature, solids

Multiple Choice

The temperature at which a substance changes from a liquid to a gas

• Melting point

• Boiling point

• Freezing point

• Condensation point

Multiple Choice

A sample of tin has a volume of 1.2 cm³. If the sample has a mass of 8.8 g, what is the density of Tin?

• 10.6 g/cm³

• 0.14 g/cm³

• 7.6 g/cm³

• 7.3 g/cm³
