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.
