The Importance of Physical

PropertiesPhysical properties are characteristics of a

substance that can be observed or measuredwithout changing the substance

Mass is a Physical

Property%Mass is the amount of matter in an obect'

Matter is anything that has mass and ta(es up

space'

This carrot is made of

matter and has mass%

+efore you answer'' Which one ta(es up more space

WeightWeight is the measure of the pull of gravity on

an obect'

Which cube has more

weight The #tyrofoamcube )* the metal cube

,olume,olume is the amount of space that an obect

ta(es up'

"ow can volume be measured

,olume can becalculated by thisformula-

Length . width . height/

Mi.ture vs' #olution mi.ture is a

combination oftwo or moredi2erent (inds ofmatter'

solution is atype of mi.ture in

which particles ofthe twosubstances aremi.ed'

#olubility3 the ability to be dissolved'

you touch itbecause theparticles thatma(e it arepac(ed tightlytogether'

Li7uid

particles movefreely enoughto slide pastone another' That way6 theycan change

shape%

Particles are

far apart andmove thefastest' Theyare able to:oat to the topand escape

into the air

;vaporation & Precipitation

;vaporation occurs whenparticles escape from a non3boiling li7uid and become agas

Precipitation occurs whenli7uid or solid water

4ondensation4ondensation changes a substance from a gas

to a li7uid'

Thin( of a cold glass ofwater on a hot day''

Water vapor in the air iscooled on the surface ofthe glass' It condensesand then forms waterdrops'

spoil6 they undergo a chemical change' Thechange in odor is a clue to the chemicalchange

is a clue to chemical changes' The bubbles ofgas that you observed form when an antacid is

dropped into water is an e.ample of change'

sign of a chemical change is the release or gainof energy by an obect' Many substances
