states of matter

• Solids particles are tightly packed together therefore meaning the particles cannot move and vibrate in their fixed positions.
• Solid particles are in a fixed regular pattern.
• Solid to liquid = melting
• Solids have very little kinetic energy due to the particles not being able to move around freely.
• liquid to solid= freezing
• Liquids particles are still close together but they aren't in a fixed position.
• Liquid particles have little kinetic energy due to particles not being able to move freely.
• Liquid to gas= evaporation/boiling.
• Solid to gas= sublimation.
• Gases have very high kinetic energy due to the particles being free to move around at rapid paces.
• Gases are not in a regular patter due to the particles moving around constantly fast and in random directions.
• Changes of state occur when intermolecular bonds are broken and new bonds are formed.
• liquids and gases are able to flow.
• Gases and liquids can spread in any container they have been placed in.
• Solids have a higher density.
