Study Notes
Chemistry Overview
- Chemistry is the study of matter, including its composition, structure, properties, and the changes it undergoes.
Branches of Chemistry
- Organic Chemistry focuses on the study of carbon-containing compounds.
Definition of Chemical
- A chemical refers to any substance with a specific composition.
Mass and Volume
- Mass measures the amount of matter present in a sample.
- Volume is the measurement of the three-dimensional space occupied by an object.
Pure Substances vs. Mixtures
- A pure substance consists of either an element or a compound, while a mixture contains multiple substances.
Properties of Substances
- Properties are characteristics that can define groups of substances and are crucial for classification.
Utility of Properties
- Properties help distinguish between different substances and are essential for classifying unknown materials.
Extensive vs. Intensive Properties
- Extensive properties, such as mass and volume, depend on the amount of matter present.
- Intensive properties, such as density and boiling point, do not depend on the amount of matter present.
Chemical Properties
- A chemical property describes a substance's capacity to undergo transformations into different substances.
Change in State
- A change in state refers to a physical change where a substance transitions from one state of matter to another.
