Chapter 13 The Molecular Model of Matter Did you read all of Chap. 13 for today? a) a) Yes Yes b) b) No No What is a Model? square4 A useful analogy we can relate to. square4 They are almost never 100% correct. square4 Different models are used to describe the same thing at different levels of detail. F4 Corsair Models of Matter square4 Continuous (Ch 12.7) square4 Molecular (Ch 13) square4 Atomic (Ch 14) square4 Nuclear Solar System (Ch 14 ) Bohr (Ch 14) square4 Quantum (Ch 16) square4 Continuous Model square4 No matter how many times we cut matter in half, it retains its properties. square4 Can we really go on cutting matter forever?

Assumptions of The Molecular Model square4 All matter is made of distinct, tiny particles which are: Too small to see with an optical microscope. Different for different materials In constant motion Governed by Newton’s laws of motion Indivisible So What? square4 Let’s face it, anyone can come up with a theory or model. The proof is in what it can explain and predict. square4 So we ask, what can the molecular theory of matter explain and predict? Evidence for the Molecular Model: Brownian Motion square4 The erratic, jittery motion of a dust speck in a fluid is strong evidence supporting the molecular model.
