Study Notes
Properties of Matter
- Matter encompasses all materials that occupy space and possess mass, including solids, liquids, and gases.
Classification of Properties
- Properties of matter are classified into physical and chemical properties.
- Physical properties can be observed without altering the substance's chemical composition.
Intensive Properties
-
Intensive properties are traits that do not depend on the amount of substance present.
-
Temperature: A measure of the warmth or coldness of a substance.
-
Malleability: The ability to be hammered or transformed into thin sheets.
-
Ductility: The capacity of a material to be stretched into a wire.
-
Diffusion: The process of matter spreading out or being dispersed.
-
Solubility: The degree to which a substance can dissolve in a solvent.
-
Freezing Point: The specific temperature at which a liquid transitions to a solid.
-
Density: The mass of a substance relative to its volume.
-
Boiling Point: The temperature at which a liquid’s vapor pressure equals atmospheric pressure.
-
Magnetism: The ability of a material to experience a magnetic attraction.
-
Electrical Properties: The capacity of a material to conduct electric current.
Extensive Properties
-
Extensive properties depend on the quantity of material present.
-
Mass: Measurement of the amount of matter, typically expressed in grams or kilograms.
-
Volume: The amount of space a substance occupies.
-
Length: A measurement of distance.
Chemical Properties
-
Chemical properties describe how matter reacts when interacted with other substances.
-
Flammability: Indicates how quickly a material can catch fire.
-
Oxidation: Occurs when a substance loses electrons during a reaction.
Specific Examples
- Water freezes at 0°C.
- Coal is burned to produce electricity for generators.
- Salt and refined sugar share a white coloration.
- 5 kg of rice and newly harvested cotton weigh the same.
- Silver tarnishes when exposed to air, forming silver oxide.
Practical Consideration
- When sneezing in a closed room, diffusion allows droplets to travel and potentially reach others.
- To avoid spreading germs when sneezing, turn away or use a tissue to cover the mouth and nose.
