Intensive Properties

​

It is the ability of a material to return to its original shape or size after being stretched or compressed.

​

​

Elasticity

It is the ability of a material to undergo permanent deformation.

A material can be bent into a new shape and it will hold that shape.​

​

Plasticity

Multiple Choice

Malleability

The ability of a material to shatter and break instead of bending

​

​Brittleness​

It is the resistance of a material to be deformed by external forces.

​

​Opacity

It is the ability of a material to let light pass through but not totally.

A transparent ​material is clear like a glass window.

Translucency

it is the ability of a material to bend without breaking.

​

​Flexibility

The property of a material that allows heat or electricity to flow.

​

​Conductivity

Multiple Choice

The glass of the window is...

• opaque

• translucent

• transparent

They are physical properties that changes with the amount of matter present.

Mass - the amount of matter in an object.

Volume - the amount of space that the object occupies.​
