Study Guide for Properties of Matter: Name______________________________ per:_____ First of all…how are you doing with the vocab? Rate yourself on how well you know each word before you study and then again right before the test. How well did you prepare? + means you are an expert, and you could explain it to anyone here. means you have heard of it, but you are not an expert. 0 means you do not know the word yet. ___matter___ ___physical property___ ___chemical property___ ___tyndall effect ___ ___viscosity ___ ___ductility___ ___malleability ___ ___ density ___ ___ hardness ___ ___physical change___ ___chemical change___ ___mixture___ ___pure substance___ ___solution___ ___ element___ ___ compound___ ___molecule___ ___atom___ ___homogeneous mixture___ ___heterogeneous mixture ___solute___ ___solvent___ Matter Classification All matter can be classified as either a substance or mixture. A substance is an element or a compound. A mixture is heterogeneous or homogeneous. Matter AKA: Ex: Ex: Ex: Ex: Ex: Classify each of the following as either substance or mixture. If it is a pure substance, write element or compound in the appropriate column. If it is a mixture, write heterogeneous or homogeneous in the appropriate column.
