Study Notes
Physical Properties of Matter
Characteristics
- Physical properties are characteristics of matter that can be observed or measured without changing its composition.
- Examples: color, shape, size, texture, smell, taste, boiling point, melting point, density.
Types of Physical Properties
- Extensive Properties: depend on the amount of matter present
- Examples: mass, volume, length
- Intensive Properties: do not depend on the amount of matter present
- Examples: density, temperature, color
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.
- Density: calculated by dividing mass by volume (density = mass/volume).
- Temperature: measured in units of Celsius (°C) or Kelvin (K) using a thermometer.
Importance of Physical Properties
- Help identify and distinguish between different substances.
- Essential in various industries, such as manufacturing, construction, and medicine.
- Used to determine the suitability of a substance for a particular use.
