Ctivity 2: Study the following properties of materials. 1. Physical properties = characteristic of matter that can be readily observed without
changing its composition
A Hardness the ability of a material to resist pressure
B. Malleability - the ability of a material to be pounded into thin sheets
C Ductility the ability of a material to be drawn into thin wires
D Porosity - the ability of a material to allow water and gases to pass through it
E Flexibility the ability of a material to bend or roll without breaking easily
F Thermal Conductivity - the ability of a material to transfer heat from one area to another
G. Brittleness the ability of a material to be easily broken
H Elasticity the ability of a material to return to its original size and shape without
breaking
II. Chemical properties = are properties that can be observed or measured only when matter
undergoes a change to become an entirely different kind of material
J. Combustibility = ability of a material to burn
K Flammability = ability of a material to ignite or easily catch fire
L. Chemical Reactivity - the ability of material to react and produce new materials when
combined with oxygen, acid, or water
M. Biodegradability = ability of a material to decompose
N. Toxicity - the degree to which a chemical substance can damage an organism
Identify the property of the given material by choosing from the given list of properties
above. Write the letter of your choice on the space provided.
