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?

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