Study Notes
Characteristics of Solids
- Solids have closely packed particles that vibrate in fixed positions, providing definite shape and volume.
Behavior of Particles in Gases
- In gases, particles are far apart and move freely at high speeds, resulting in no fixed shape or volume.
Chemical vs. Physical Change
- A chemical change involves the formation of new substances with different properties, while a physical change alters the form or appearance without changing the substance itself.
Defining Characteristic of Solutions
- Solutions are homogeneous mixtures where one substance (solute) is completely dissolved in another (solvent), resulting in a uniform composition.
Distinction Between Mixtures and Compounds
- Mixtures are combinations of two or more substances that retain their individual properties, while compounds consist of two or more elements chemically bonded together, resulting in new properties.
