Matter Most basic building block. Must have mass and volume Elements Simplest form of matter, can't decompose any further Molecules Two or more atoms "linked" together Compounds Mixes of two or more elements bonded together Sig Fig.- x & / As many as the least number Sig Fig.- + & - As many as the least behind the decimal point Law of Definite Composition Components in a compound always have the same ratio by mass Law of Multiple Proportions Ratios of elements that combine to m...

Conduction - correct answer direct transfer of energy from molecule to molecule via direct molecular collsions What are the best and worst conductors? - correct answer Worst= gases Best= metals Convection - correct answer heat transfer by physical motion; only takes place in fluids and gases. Heat energy is transferred AWAY from the source. Radiation - correct answer transfer of energy by electromagnetic waves. Radiation can travel through a hard vacuum. Ex: energy from sun specif...
