Study Notes
Physical and Chemical Properties
- Physical properties can be tested without changing the substance's identity.
- Chemical properties require a change in the substance to be observed.
Physical and Chemical Changes
- Physical changes alter the form of a substance without changing its composition (e.g., tearing paper).
- Chemical changes result in the formation of new substances through reactions (e.g., mixing chemicals).
Distinguishing Properties and Changes
- Properties are characteristics of a substance (e.g., color, mass).
- Changes refer to transformations that modify the substance itself (e.g., cooking food).
Examples of Physical Properties
- Color
- Smell
- Volume
- Mass
- Density
Examples of Chemical Properties
- Reactivity with oxygen
- Flammability
- Heat reactivity
Examples of Physical Changes
- Tearing a piece of paper
- Chewing food
- Sharpening a pencil
Examples of Chemical Changes
- Mixing two substances to create a new one
- Digesting food
- Decomposition processes
- Burning materials
- Cooking food
Key Physical Properties Definitions
- Viscosity: Measurement of a liquid's resistance to flow.
- Density: Mass per unit volume of a substance.
- Electrical Conductivity: Ability of a substance to conduct an electrical current.
- Thermal Conductivity: Rate at which a substance transfers heat.
Substance States and Characteristics
- State/Phase: The physical form in which a substance exists (solid, liquid, gas).
- Solubility: Capacity of a substance to dissolve in another.
- Ductility: Ability to be drawn into wires.
- Malleability: Ability to be rolled into thin sheets (e.g., tin foil).
- Surface Tension: Force acting on the surface particles of a liquid.
