MASS OR VOLUME
A PHYSICAL CHANGE INVOLVES A CHANGE IN _________ , ________ , ________ , OR __________. (FILL IN TWO BLANKS)
SIZE, SHAPE, FORM, STATE OF MATTER
CHANGE IN SIZE, SHAPE, FORM, OR STATE OF MATTER IN WHICH THE MATTER’S IDENTITY STAYS THE SAME
PHYSICAL CHANGE
WHAT THREE PARTICLES MAKE UP ATOMS
PROTONS, NEUTRONS, ELECTRONS
NAME TWO SIZE INDEPENDENT PROPERTIES
MELTING POINT, BOILING POINT, DENSITY, ELECTRICAL CONDUCTIVITY, SOLUBILITY, THERMAL CONDUCTIVITY
TRUE OR FALSE: THE IDENTITY OF MATTER CHANGES DURING A PHYSICAL CHANGE
FALSE, IT DOES NOT CHANGE
ANYTHING THAT HAS MASS AND TAKES UP SPACE
MATTER
WHAT ARE THE TWO MAIN CLASSIFICATIONS OF MATTER
SUBSTANCE AND MIXTURE
NAME TWO PHYSICAL PROPERTIES THAT CAN BE USED TO SEPARATE MIXTURES
STATE OF MATTER, BOILING POINT, MELTING POINT, DENSITY, VOLUME, SOLUBILITY
WHEN A SOLID CHANGES DIRECTLY TO A GAS (SKIPPING LIQUID STATE)
SUBLIMATION
AMOUNT OF MATTER IN AN OBJECT
MASS
THE NUMBER OF PROTONS IN AN ATOM DETERMINES AN ELEMENT’S ______________
ATOMIC NUMBER
TRUE OR FALSE: THE DENSITY OF AN OBJECT CAN BE FOUND BY DIVIDING ITS LENGTH BY ITS WIDTH
FALSE, DENSITY IS MASS DIVIDED BY VOLUME
STATE OF MATTER CAN BE CHANGED BY ADDING __________ ENERGY
THERMAL
________ IS THE ABILITY TO DISSOLVE
SOLUBILITY
SUBSTANCES THAT ARE NOT EVENLY MIXED
HETEROGENEOUS MIXTURE
WHAT IS THE DIFFERENCE BETWEEN A SUBSTANCE AND A MIXTURE
BOTH ARE MATTER. SUBSTANCE - COMPOSITION IS ALWAYS THE SAME. MIXTURE CAN VARY IN COMPOSITION
HOW IS MASS DIFFERENT FROM WEIGHT
MASS IS HOW MUCH MATTER IS PRESENT, WEIGHT IS THE PULL OF GRAVITY ON MATTER
GIVE AN EXAMPLE OF WATER IN EACH STATE OF MATTER
SOLID - ICE, LIQUID - WATER, GAS - WATER VAPOR
WHAT IS MEANT BY CONSERVATION OF MASS
MASS IS CONSERVED BECAUSE IT REMAINS THE SAME AFTER A CHANGE, SUCH AS A PHYSICAL CHANGE
