Classification of
Materials
One common way is to classify materials
is according to physical properties such as strength,
hardness, density, flexibility, electrical conductivity, thermal
conductivity boiling point and melting point.
Is waterproof considered as a
physical property? What is the science definition for water proof?
I am given the understanding that any material that does not
allow water to pass through is waterproof.
Please advise.
Thank you
What level are you studying at? There is no chemistry syllabus that
requires the definition of 'waterproof'. If you're at secondary
school level, then the definition that you yourself just gave will
suffice.
And yes, being 'water proof' may be considered a physical
property. Because no chemical reaction is involved when the
material comes into contact with water.
