Study Notes
Density and Mass
- Density is defined as the mass per unit volume of a substance.
- Mass represents the amount of matter contained in an object.
Volume and Weight
- Volume refers to the amount of space occupied by an object.
- Weight is the measure of gravitational force acting on an object.
States of Matter
- Solids have a definite shape and volume, with particles arranged in two types:
- Amorphous solids have a random particle arrangement.
- Crystalline solids have particles arranged in a regular, repeating three-dimensional pattern.
- Liquids possess a definite volume but lack a definite shape, allowing them to take the shape of their container.
- Gases do not have a definite shape or volume, expanding to fill available space.
Forces and Properties
- Cohesion is the attraction between particles of the same kind, contributing to the characteristics of liquids and solids.
- Adhesion is the attraction between unlike substances, important for interactions such as liquid on surfaces.
- Surface tension is the net force acting on liquid particles at the surface, affecting behaviors like droplet formation.
- Viscosity measures a liquid's resistance to flow, influencing its behavior in various applications.
Phase Changes
- Phase change refers to the transition of a substance from one state (phase) to another.
- Types of phase changes include:
- Evaporation: transition from liquid to gas.
- Condensation: transition from gas to liquid.
- Sublimation: transition from solid directly to gas.
- Deposition: transition from gas directly to solid.
Changes and Reactions
- Physical change involves alterations in physical properties without changing the substance itself.
- Chemical change results in the formation of new substances with unique properties.
- Common chemical changes include:
- Combustion: burning of substances.
- Oxidation: a reaction involving the combination of a substance with oxygen.
Thermal Expansion
- Thermal expansion describes the increase in volume of a substance due to an increase in temperature.
Pressure
- Pressure is defined as the force exerted on an object per unit area, affecting various physical and chemical processes.
