Study Notes
States of Matter
- Matter exists in different states based on the arrangement and distance of its particles.
-
Solid:
- Retains a definite shape and volume.
- Particles are tightly packed with minimal movement.
- Highly resistant to compression.
-
Liquid:
- Has a definite volume but conforms to the shape of its container.
- Particles are further apart, allowing for movement.
- Cannot be significantly compressed.
-
Gas:
- Lacks a definite shape and volume.
- Particles are randomly arranged and have high mobility.
- Easily compressible by reducing the container's volume.
Physical and Chemical Properties
- Substances exhibit different properties due to variations in atomic composition and structure.
- Examples include:
- Kerosene (flammable) vs. water (non-flammable).
Physical Properties
- Can be measured or observed without creating a new substance.
-
Boiling Point:
- Temperature at which a liquid turns into vapor.
- Identity of the substance remains unchanged during phase transition.
-
Melting Point:
- Temperature at which a solid transitions into a liquid.
-
Phase Changes:
- Evaporation: Liquid to gas.
- Condensation: Gas to liquid.
- Deposition: Gas to solid.
- Sublimation: Solid to gas.
- Melting: Solid to liquid.
- Freezing: Liquid to solid.
Chemical Properties
- Require a chemical reaction to be observed, resulting in a change of identity.
-
Flammability:
- A substance's ability to ignite and burn.
- Example: Burning hydrogen gas produces water.
-
Toxicity:
- The capacity of a substance to harm living organisms.
- More toxic substances require smaller amounts to cause harm, interfering with physiological processes.
