Physical Properties and Measurements

Electrical conductivity

The measure of how easily an electric current

Thermal conductivity

The measure of how easily heat flows through it

Melting point

The temperature at which a substance changes from the solid state to liquid state

Boiling point

The temperature at which a substance changes from the liquid state to gaseous state

Strength

The ability of a material to support a heavy load without changing its shape permanently

Hardness

The ability of a material to withstand scratches

Flexibility

The ability of a material to bend without breaking, and return its initial shape and size after bending

Density

The amount of matter an object has in proportion to its volume

Conditions/Assumptions when using the displacement method

• The displacement method can only be used on waterproof objects/objects that do not absorb water

• The displacement method also assumes that the volume of the submerged string is negligible
