States of Matter — properties?
Solids: fixed shape, particles vibrate; liquids: shape of container, particles move; gases: spread out, particles move freely.
States of Matter — properties?
Solid: fixed shape; Liquid: shape of container; Gas: no fixed shape or volume.
Particle structures — role?
Determine properties and behavior during phase changes.
Particle arrangement — solids vs gases?
Solids: fixed, regular; Gases: spread out, random.
Changes of State — mechanism?
Energy transfer overcomes or forms intermolecular forces.
Melting point — definition?
Temperature where solid becomes liquid.
Boiling point — definition?
Temperature where liquid turns to gas.
Phase changes — energy transfer?
Energy overcomes or forms intermolecular forces.
Kinetic Particle Theory — role?
Explains states and phase changes based on particle energy.
Heating curve — phase change indication?
Horizontal: phase change; Rising: temperature increase.
