Study Notes
Chemistry Branches
- Chemistry is divided into branches, and one of them focuses on the study of the composition, structure, properties, and reactions of matter.
Scientific Method
- The scientific method is a step-by-step process, but it does not include "accidentally discovering a phenomenon" as one of its steps.
Physical Properties
- A physical property of a substance is its ability to change phase from a solid to a liquid, such as ice (solid) to water (liquid).
Measurement Units
- In chemistry, a common unit of measurement is the mole (mol).
Ideal Gas Law
- The ideal gas law is represented by the equation: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
