Study Notes

Definitions

Physical Properties: Observable or measurable attributes of a material that do not alter its composition.
Chemical Properties: Characteristics that become apparent during a transformation in the material's composition.

States of Matter

Solid State: Has a fixed shape and volume, with particles closely packed in a defined arrangement.
Liquid State: Maintains a definite volume but adapts to the shape of its container due to looser particle arrangement.
Gas State: Lacks both a defined shape and volume, expanding to fill the entire space of the container.

Types of Substances

Pure Substances: Composed of a single type of particle, exhibiting consistent and uniform composition throughout.
Mixtures: Combinations of two or more pure substances that retain distinct properties of the individual components.

Categories of Mixtures

Heterogeneous Mixture: Contains varied components that do not combine uniformly, resulting in different proportions across the mixture.
Homogeneous Mixture: Exhibits uniform properties such as texture, color, smell, or taste throughout the entire mixture.
