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
