Solid – has definite shape and Volume Mass – bigat Volume – amount ng nasa loob History of atom: Leucippus Democritus Atom = “uncuttable” Latin word – “atomos” John Dalton Atom = just a tiny solid sphere Molecular theory of matter: Molecules are bigger than atoms All matter = Molecules spaces between molecules molecules r always moving(?) attract one another Viscosity - The stronger the attractions between the particles of a liquid, the more viscous the liquid is. Phase change → change in the energy faster or slower when heat energy is absorbed endothermic exothermic Intramolecular forces → Palapit Intermolecular forces → Papalayo Molecules are vibrating Liquid bubble → bubbles are Transfering gases Molecules: Slow →cold Fast → hot Temperature is a measurement of the amount of heat energy Freezing/solidification →liquid to solid Melting →solid to liquid Sublimation →solid to gas Deposition →gas to solid Evaporation →liquid to gas Condensation →gas to liquid Matter → is made up of tiny particles called “atoms”. Atoms → are the smallest Particles of matter
