Kenetics And Diffusion Flashcards
Describe the arrangement, movement and energy of particles in solids
movement - vibrate about their fixed positions but do not move freely.
Arrangement - tightly packed.
Energy - The particles in a solid have the least amount of kinetic energy compared to liquids and gases.
Describe the arrangement, movement and energy of particles in liquids
Arrangement - Particles in a liquid are closely packed but not in a fixed arrangement.
Movement - Particles in a liquid move more freely than in a solid. They can slide past one another, giving liquids the ability to conform to the shape of their container.
Energy - Particles have more kinetic energy than in solids but less energy than gases
Describe the arrangement, movement and energy of particles in gases.
Arrangement - Particles are far apart and not in any fixed arrangement.
Movement - Particles move rapidly and freely in all directions. The movement is random and constant.
Energy - Particles have the highest amount of kinetic energy compared to solids and liquids.
name the interconversions between solids, liquids and gases.
Solid to Liquid: Melting
Liquid to Solid: Freezing
Liquid to Gas: evaporation
Gas to Liquid: Condensation
Solid to Gas: Sublimation
Gas to Solid: desublimation
Describe how to interconvert between solids, liquids and gases.
Solid to Liquid - Heat a solid until it reaches its melting point.
Liquid to Solid - Cool a liquid until it reaches its freezing point.
Liquid to Gas - Heat a liquid until it reaches its boiling point for rapid vaporization (boiling), or allow it to evaporate at temperatures below the boiling point.
Gas to Liquid - Cool a gas until it reaches its condensation point.
Solid to Gas - Heat a solid until it directly converts to a gas without passing through the liquid phase.
Gas to Solid - Cool a gas until it directly converts to a solid without passing through the liquid phase.
