PHYSICAL AND CHEMICAL PROPERTIES OF MATTER

• • Matter is grouped according to their similarities in properties.
• Properties refer to the DISTINGUISHING characteristics to IDENTIFY certain material.
• • A number of materials around you have their own peculiar properties that you can use to identify them.
• The properties of matter can be grouped into two general categories: PHYSICAL and CHEMICAL.
• • PHYSICAL PROPERTY - can be measured and observed without changing the composition or identity of a substance.

   

  • No new material is produced

   

  • Color, odor, taste, volume, hardness, density, boiling point, texture, electrical conductivity, solubility, malleability, and tensile strength are examples of Physical properties of matter.

   
• The Physical properties of matter are further classified into INTENSIVE and EXTENSIVE.
• • Intensive properties of matter -are those that are not dependent on the kind or quality of matter.
  • Texture, color, odor, hardness and density are some example of intensive properties.
• • Extensive properties of matter - are  those that depend so much on the amount or quantity of matter.
  • Examples are volume, mass, length, and area.
• • CHEMICAL PROPERTIES OF MATTER - are those that result when a new substance is produced.
  • Examples:
  • The addition of fertilizer to the soil causes the plants to grow robust.
  • The exposure of peeled potatoes to air causes it to oxidize and so, turn brown.
  • Other examples of chemical properties are flammability, corrosiveness and reactivity with acids.
