Study Notes

Physical Properties of Matter

Characteristics of Physical Properties

  • Can be observed and measured without changing the composition of the substance
  • Examples: color, shape, size, texture, odor, taste, melting point, boiling point, density

Types of Physical Properties

  • Extensive Properties: dependent on the amount of substance
    • Examples: volume, mass, length
  • Intensive Properties: independent of the amount of substance
    • Examples: density, melting point, boiling point

Measurement of Physical Properties

  • Mass: measured in units of grams (g) or kilograms (kg) using a balance
  • Volume: measured in units of milliliters (mL) or liters (L) using a measuring cylinder
  • Length: measured in units of meters (m) or centimeters (cm) using a ruler
  • Density: calculated by dividing mass by volume (density = mass / volume)

Importance of Physical Properties

  • Used to identify and distinguish between different substances
  • Crucial in various industries such as manufacturing, construction, and healthcare
  • Essential in our daily lives, e.g., cooking, cleaning, and personal care
