- Four States of Matter
- Solid Liquid Gas Plasma
- Basis of Classification of the Four Types
- 1.) Based upon particle arrangement 2.) Based upon energy of Particles 3.) Based upon distance between particles
- Solids
- a.)tightly packed, vibrating about a fixed position B.) definite shape and definite volume C.) infinite number of free surfaces
- Liquids
- A.) tightly packed, but are far enough apart to slide over one another B.) indefinite shape and has a definite volume C.) One free surface D.)Viscosity liquid's resistance to flow. The stronger the attraction between the molecules of a liquid, the greater its viscosity.
- Viscosity
- liquid's resistance to flow. The stronger the attraction between the molecules of a liquid, the greater its viscosity.
- Gases
- A.) Particles are very far apart and move freely. B.) indefinete shape and volume C.) no free Surfaces
- Boyle's Law
- volume and pressure are inversely related. As the gas's pressure increases, the volume decreases by the same amount.
- Charles' Law
- Temperature are related: as the temperature of gas changes, the volume of the gas increases by the same amount.
- What is the fourth type of matter?
- Plasma
- What happens when plasma is heated?
- It becomes ionized.
- What does Ionized mean?
- one or more of the electrons have been stripped off the gas molecule.
- For most materials, what temperature does ionization occur?
- 10,000 degree Celcius
- What are the six types of Phase changes?
- Melting Boiling Evaporation Condensation Sublimation Deposition
- What is melting point?
- the temperature at which solid and liquid phases coexist with one another. T
- True or False: The temperature of the freezing point is the same as the temperature of the melting point.
- TRUE: Think about water: Ice melts at 0 degrees Celcius/32 degree F, and liquid water also freezes at 0 degree C/32 degrees F.
- What is the temperature at which liquids becomes a gas called?
- Boiling Point
- What happens when liquid reaches the boiling point?
- Molecules are heated and begin moving so fast that they escape out of the liquid state and become a gas.
- At boiling point, liquid and vapor (gas) are at what?
- equilibrium
- TRUE or FALSE: Different materials have different boiling points.
- TRUE: Boiling point of water is 100 degree C/212 degree F.
- When liquid changes to a gas is called_________.
- Evaporation
- What happens during evaporation?
- Molecules escape from the liquid and become a gas.
- What is the result of evaporation?
- Temperature Drops
- When gas changes into liquid is called ________.
- Condensation
- TRUE OR FALSE: Molecules in water vapor collect together to form small droplets.
- TRUE
- TRUE OR FALSE: Clouds are large groups of water droplets.
- TRUE
- TRUE OR FALSE: When the droplets get large enough they fall to Earth as rain.
- TRUE
- Sublimation is________.
- the transition from a solid to gas.
- True or False: When old ice cubes in the freezer shrink in size is an example of sublimation because the water has changed to a vapor.
- TRUE
- Deposition is _____.
- process in which gas transforms into a solid.
- TRUE or FALSE:Snow forms in clouds is an example of deposition.
- TRUE: Deposition is when vapor changes to a solid without becoming a liquid.
- Put the energy of particles in order. Highest to lowest.
- Plasma: very high Gas: high Liquid: medium Solid:low
