physical and chemical properties

Physical property

A physical property is describing how a substance looks not changing into a new substance

Chemical properties

Describes the behaviour of a new substance aka changes substances completely and can not go back to original state

State

Solid liquid or gas

Malleability

Ability to bend into different shapes

Ductility

Can be pulled into thin wires

Lustre

Shiny or dull

Magnetism

Tendency to be attached to a magnet

Conductivity

Ability to conduct electricity ( part of physical property’s )

Melting and boiling point

Temperature at which a substance changes state ( part of physical property’s )

Solubility

The ability to dissolve ( physical property)

Viscosity

How easy a liquid flows for example water has low viscosity corn syrup has high viscosity

Density

mass divided by volume

Combustibility

The ability of a substance to burn ( chemical property cannot be reversed )

Reactivity

How easy a substance reacts with another substance ( chemical property )

Toxicity

Degree to which substances react in the body to produce harmful substances

What dose qualitative mean

Observation aka what u see

What are some ways u can tell a substance was chemically changed?

1 bubbles forming, 2 colour change ( unexpected and permanent) 3 volume change 4 electricity is produced 5 change in smell or taste 6 THE CHANGE IS NOT EASILY REVERSED 7 light is emitted 8 burned

Use chat gtp to ask it chemical and physical change things
