UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Read pg. 8 (beginning with 1st full paragraph), pg. 329-332, 333-336, 337-341 • Write at least 4 important facts, in complete sentences, about each state of matter that would help you answer the lesson essential question. • Number each fact! • Write at least 3 Questions that you still have over the reading.
Unit 1: Matter Concept: Composition of Matter
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • 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: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? Bell Ringer 09/06/2012 Write question and answer. Explain the difference between an amorphous solid and a crystalline solid.
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Solids • Holds shape! Why? • Definite shape (non-fluid)and Definite volume because packed tightly • 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
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • 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; but, still have a definite shape • No definite melting points
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Liquids • Definite volume but indefinite shape • Take shape of container • Particles free to move/slide past one another; but, still held together by intermolecular forces (attraction between particles) • 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
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Surface Tension • Drawing molecules together to decrease surface area • Predict: How many drops of water can you 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 the reading of the graduated cylinder?
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Gases • Indefinite shape, indefinite volume • Too much energy to remain attached. Particles 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: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Diffusion • Spontaneous mixing of particles of two substances caused by random motion
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • KE = ½ mv² • KE = Kinetic Energy • m = mass of particle • v = speed of particle
UEQ: In dealing with matter, how are composition, structure, properties and energy related? LEQ: How do the particle arrangement and energy differ between the states of matter? • Exit Ticket: • 1. Which state of matter has definite shape and definite volume? • 2. Which state of matter has an indefinite shape and indefinite volume? • 3. Which state of matter has an indefinite shape and a definite volume?
