TOPIC 4 Expansion and Contraction - Basic Knowledge 101
210 MHR Heat and TemperatureTOPIC4 Expansion and Contraction As materials warm up, the particle model of matter says that their particles move faster and spread apart. We expect substances to expand(increase in volume) as their temperature rises. Falling temperaturemeans that average particle motion is slowing down. It seems logical toexpect substances to contract(decrease in volume) as they can check those predictions by observing the behaviour of common pure substances. A pure substance is a type of matter that ismade of only one kind of particle. On Earth, a pure substance mayexist as a solid, liquid, or gas. These are the three states or phases ofmatter. Gold, oxygen, and water are examples of pure the illustrations to review the key characteristics of each three states of matterIn the solid state, materials keep their shape and size. Solids like icehave a definite shape and volume and cannot be compressed into asmaller space.
