Study Notes
Branches of Chemistry
- The branch of chemistry that focuses on material interactions and transformations is known as Physical Chemistry.
- It combines principles of physics and chemistry to study properties of materials and how they undergo changes.
Subdiscipline of Chemistry
- Biochemistry is the subdiscipline that traditionally studies living organisms.
- It explores chemical processes and substances that occur within and relate to living systems.
States of Matter
- The state of matter that assumes the shape of its container while maintaining a definite volume is Liquid.
- Liquids have a fixed volume but can change shape to fill their container.
Properties of Gases
- The property of gases described as the force exerted per unit area by gas molecules is known as Gas Pressure.
- This pressure results from molecular collisions against the surfaces of the container.
Phase Transition
- The process whereby a substance changes directly from a solid to a gas, bypassing the liquid state, is known as Sublimation.
- Common examples of sublimation include dry ice transitioning to carbon dioxide gas and the sublimation of iodine.
