There are many properties you can not see very well such as:

• hardness, color, brittleness, reflectivity

• solubility, electrical conductivity, thermal conductivity

• weight, taste, uses

• skills, cooking temperature, boiling point

Solubility is:

• a property that describes whether a substance can dissolve in another substance

• a substances ability to find a solution to a problem

• how well a substance boils

• how often a substance explodes

Electrical conductivity is...

• how well a substance allows electric current to pass through it

• how well a substance does the electric slide

• how well a substance boils

• how well a substance lights up

Thermal conductivity is...

• how well a substance allows heat to pass through it

• how well a substance allows electricity to pass through it

• how well a substance dissolves in another substance

• how well a substance drinks from a thermos
