Physical/Chemical Properties LESSON 1 Flashcards
A physical property is…
a characteristic or description of a substance that may help to identify it. Unlike a chemical property, a physical property does not involve a substance becoming a new substance. Some physical properties can be observed by using your senses. Others are observed using simple tests and measurements.
Colour
e.g. blue, red, white, …
Optical clarity
Either transparent, translucent and opaque.
Crystal shape
Definite structures of cubes or blocks with a regular pattern
Density
Amount of matter per unit volume of that matter
Ductility
Ability of a solid to be stretched into a long wire-like shape
Hardness
Determined by the resistance to be scratched; rated on a scale of 1-10 with diamond being rated a 10
Texture
The “feel” of an object (e.g. waxy, smooth, rough)
Lustre
Ability of an object to reflect light (i.e. shiny, dull)
Viscosity
The resistance of a liquid to flowing
Malleability
Ability to be hammered into thin sheets
Solubility
Ability of a substance (solute) to dissolve in another substance (solvent) like water
State of matter
Condition of being a solid, liquid or gas
Taste
e.g. sweet, sour, bitter, salty
Qualitative physical property examples:
Colour
Odour
State
Texture
Lustre
Malleability
Quantitative physical property examples:
Viscosity
Melting point
Boiling point
Solubility
Hardness
Conductivity
Density
How would you describe a popsicle using the physical property?
Cold, rectangular, hard, 10cm long, sweet, red and orange, 100 g
A chemical property is…
a characteristic of matter that can only be observed when one substance changes in to a different substance, such as iron into rust
Corrosion
Reacts with oxygen to produce rust
Flammability
Ability to burn
Chemical property qualitative/quantitative examples:
Corrosion
Flammability
