Chapter 10 Objectives

• describe the motion of gas particles according to kinetic molecular theor
• interpret gas pressure in terms of kinetic theory
• describe the nature of a liquid in terms of the attractive forces between the particles
• differentiate between evaopration and boiling point of a liquid using kinetic theory
• describe how the degree of organization of particles distinguishes solids from gases and liquids
• distinguish between a crystal lattice and a unit cell
• explain how allotropes of an element differ
• interpret the phase diagram of water at any given temperature and pressure
• describe the behavior of solids that change directly to the vapor state and recondense to solids without passing through the liquid state
