Solid, Liquid, Gas 1 of 14 Solid characteristics Strong, lattice arrangement. 2 of 14 Liquid characteristics Weak forces, random particle arrangement, don't keep shape. 3 of 14 Gas characteristics Very weak forces, move constantly, hotter = pressure increases. 4 of 14 Solid to liquid? Melting 5 of 14 Liquid to gas? Evaporation 6 of 14 Solid to gas? Sublimation 7 of 14 Gas to liquid? Condensing 8 of 14 Liquid to solid? Freezing 9 of 14 What happens when a solid/liquid is melted? Particles gain more energy, move about more, which weakens forces and causes expansion, until attractions between forces have been destoryed. 10 of 14 What is diffusion? Movement of particles through a liquid or gas, from a place of lots of particles to fewer particles. 11 of 14 Mass number = ? Protons and electrons. 12 of 14 Atomic number = ? Protons. 13 of 14 What is a molecule! A group of atoms. 14 of 14
