Study Notes
Characteristics of Matter
Solids
- Have definite size, shape, hardness, texture, and color.
- Exhibit higher density compared to liquids and gases, meaning mass per unit volume is greater.
- Physical properties can be easily observed and identified through practical experiments.
Liquids
- Contain fewer molecules than solids, leading to increased molecular distance.
- Molecules are held together by sufficient attractive forces to maintain a constant volume.
- Volume stays consistent, but shape is not fixed, adapting to the container.
Gases
- Lack a fixed shape and occupy the entire volume of their container.
- Extremely weak intermolecular forces result in negligible attraction between gas molecules.
- Gases exert pressure uniformly in all directions on the walls of the container.
Conversion of States of Matter
- Melting occurs when solid ice is heated, converting it to liquid.
- Vaporization is the process where liquid turns into gas upon further heating.
- Gas can be cooled and converted back to liquid (liquefaction), and further cooling transforms it into solid (solidification).
