Section 3

Question Answer
What is a substanceHas distinct properties and composition that does not vary from multiple samples
What two types of substances are thereElements and compounds
What specifics does an element have when it comes to substancesCannot be broken down further
What specifics do compounds have when it comes to substancesIt can be broken down further to simpler substances
What are mixtures and what types are therephysical mixing and exhibit the properties of what has been mixed. homogenous and heterogenous
Physical propertiescan be observed without without changing a substance into another substance. Ex. boiling point, density, mass, volume
Chemical propertiesCan only be observed when substance is changed to another substance. flammability, corrosiveness, reactivity with acid
Intensive propertiesAre independent in the amount of the substance that is present. Density, boiling point, color
Extensive propertiesDepend upon the amount the substance present. Examples include mass, volume, energy
