  • Grab your folder!!!!
  • Have out reflections/notes from yesterday to be stamped!
  • Look at the display in front of the room…
  • Describe, in complete sentences, what you see in each box.
  • Ask the people at your table your 2 questions and see if they can answer them.

Work on Test corrections when you are finished!!!

leq what are the differences among solid liquids gases and plasmas
LEQ: What are the differences among solid, liquids, gases, and plasmas?
  • Pre-read Chapter 16 Section 1
    • Write 3 important facts, in complete sentences, about each state of matter that would help you answer the lesson essential question.
    • Number each fact!
    • Write 2 Questions that you still have over the reading.
    • This will count as your reflection tonight!

  • Choose 1: How to do Vocabulary:
    • Write word and definition. Underline and highlight vocabulary word.
    • Write word on front and definition on back of index cards.
    • Create a poem or rap of vocabulary words and definitions.
    • Create foldable with words and definitions.
    • Create a crossword puzzle. Also make answer key!!!

  • Write Question and Answer
  • What is capillary action?

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • What are the 3 assumptions to kinetic theory?
  • All matter composed of small particles (atoms, molecules, ions)
  • Particles are in constant random motion
  • Particles are colliding with each other and the walls of their containers
  • Overall, kinetic energy is how fast the molecules are moving and will do so at all temperatures.

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Solids
  • Holds shape! Why?
  • Definite shape and Definite volume
  • Not compressible (naturally) because packed tightly
  • Usually most dense phase of a substance because packed tightly
  • Exception: water
  • Definite melting points. Least amount of energy. Movement of particles is slow and around fixed points; but, increases with increase in temperature.
  • Low rate of diffusion b/c low mobility of particles
slide9

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Two types of Solids
  • Crystalline solid
    • Particles are in an orderly, geometric, repeating pattern
    • Have definite melting points
  • Amorphous solid (plastics and glass)
    • Particles are arranged randomly
    • No definite melting points
slide10

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Liquids
  • Definite volume but no definite shape
  • Take shape of container
  • Particles free to move/slide past one another; but, still held together by intermolecular forces
  • Cannot be compressed under common pressure
  • Can transmit pressure equally in all directions
  • Usually less dense than solids; but, more dense than gases
  • Diffuses at average speed
slide11

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Surface Tension
    • Drawing molecules together to decrease surface area
    • Predict: How many drops of water do you think will fit on a penny? Was your prediction correct?
  • Capillary Action
    • When surface of a liquid and solid meet, surface of liquid molecules are pulled upward, against the pull of gravity, along surface of solid
    • Meniscus
    • Observation: What is reading on the graduated cylinder?
slide12

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Gases
  • No fixed shape, no fixed volume
  • Too much energy to remain attached. Particles vibrate at high speeds.
  • Gas takes shape of container by expanding
  • Less dense than solids and liquids
  • Still considered a fluid
  • Can be compressed easily with very little pressure. However, once it is contained, it want to escape the container.

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Diffusion
  • Spontaneous mixing of particles of two substances caused by random motion
slide14

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Plasmas
  • Once molecule is superheated, electrons leave the atoms in the molecules
  • +/- charged particles
  • Stars, lightening bolts, neon/fluorescent bulbs, auroras
slide15

UEQ: How does the structure of matter influence its physical and chemical behavior?LEQ: What are the differences among solid, liquids, gases, and plasmas?

  • Exit slip
  • State of matter with indefinite volume and indefinite shape
  • State of mater with definite volume and definite shape
  • State of matter with definite volume and indefinite shape
slide16

  • Bell Ringer 09/07/2012
  • Describe and illustrate the physical differences among solids, liquids, and gases in terms of their mass, volume, density, shape, and particle arrangement.
