Study Notes
- Physical properties are characteristics of matter that can be observed and measured without changing the substance's identity
- Intensive properties are dependent on the state of matter and do not change with the quantity of matter, examples include:
- Boiling point
- Density
- Color
- Odor
- Temperature
- Refractive index
- Luster
- Hardness
- Ductility
- Malleability
- Electrical conductivity
- Solubility
- Extensive properties depend on the quantity of matter, examples include:
- Volume
- Mass
- Size
- Weight
- Length
- Density is defined as the mass of a unit volume of a material and is classified as an intensive property because it is the ratio of mass and volume
- Odor is a physical property that determines distinctive smells and is an intensive property since it does not depend on the quantity of matter
- Color is an observable trait that determines the appearance of matter and is an intensive property
- Hardness is the ability of a material to resist fracture and is an intensive property
- Length is the longest dimension of an object and is an extensive property
- Melting point is the temperature at which a substance melts and is an intensive property that can vary depending on pressure. It is expressed in Kelvin, degrees Celsius, degrees Fahrenheit, or degrees Newton.
