States of Matter Solids, Liquids & gases State of matter Definite Mass? Definite Shape? Definite volume? Particle Energy Particle Spacing Examples Solid of course! YES YES vibrates back and forth close :::::::::: ice tightly packed All matter has mass! Liquid of course! YES YES flows around each other more spread out water more than solid. ‘. ‘. ‘ All matter has mass! loose, but together Gas of course! *NO *NO more than liquid spread out water vapor ‘. ‘. ‘. All matter has mass!. ‘ ‘ all over the place! Plasma of course! *No *No + charged - spread out stars All matter has mass! * Particles fill neon signs container it is in

Solid definite shape definite volume Crystalline solids - particles in a regular repeating pattern - has a definite melting point - ex. crystals, sugar, salt Amorphous solids - particles NOT in a regular repeating pattern NO definite melting point ex. plastics, glass, candles

Liquid no definite shape definite volume Fluid = a substance that flows Surface Tension = Viscosity = the resistance to flow high viscosity = flows slow ex. honey low viscosity = flows quickly ex. water

Gas no definite shape no definite volume Fluid - a substance that flows

Boyle’s gas law volume vs. pressure ViP Boyle (volume-inverse-pressure) Volume and pressure are inversely related. volume pressure Temperature is constant (does not change)

Charles’ gas law temperature vs. volume “Charles watches direct TV” Temperature and volume are directly related (go in the same direction) Temperature Volume Volume Temperature Pressure remains constant (pressure does not change)

temperature vs. Pressure Direst relationship between temperature and pressure. Temperature Pressure
