  • 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!


Vocabulary

Vocabulary

  • 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!!!

  • Kinetic theory

  • Property

  • Density

  • Physical property

  • Chemical property

  • Matter

  • Volume

  • Write Question and Answer

  • What is capillary action?


Unit 1 matter structure and properties

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.


Unit 1 matter structure and properties

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


Unit 1 matter structure and properties

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


Unit 1 matter structure and properties

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


Unit 1 matter structure and properties

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?


Unit 1 matter structure and properties

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


Unit 1 matter structure and properties

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

  • 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
