FINISHING UP PHYSICAL PROPERTIES AND QUIZ REVIEW JUST WANT TO MAKE SURE WE COVERED IT ALL….

PHASE CHANGE IT IS THE TRANSITIONS BETWEEN SOLID, LIQUID, AND GAS ITEM CHANGES STATES OF MATTER

WATCH HOW THE PARTICLES MOVE IN THE DIFFERENT STATES OF MATTER PLEASE SKETCH THIS IN YOUR NOTE BOOKS

GAS GAS HAD NOT DEFINITE VOLUME SO IT’S VOLUME WILL CONFORM WITH THE CONTAINER IT IS IN. REMEMBER THE BUBBLE WE MADE?? VOLUME OF GAS DEPENDS ON THE SIZE OF THE CONTAINER. REMEMBER VOLUME IS THE AMOUNT OF SPACE MATTER TAKES UP. VOLUME WILL DECREASE IF IT IS PUT INTO A SMALLER CONTAINER.

THINK ABOUT…. EVAPORATION- PHASE CHANGE THAT OCCURS FROM THE SURFACE OF A LIQUID MELTING POINT- TEMPERATURE AT WHICH A SOLD WILL MELT (ANY SOLID) FREEZING POINT- TEMPERATURE AT WHICH A LIQUID BECOMES A SOLID (ANY LIQUID)

BOILING POINT THE TEMPERATURE WHEN A LIQUID IS HEATED AND THE PRESSURE INSIDE THE LIQUID FORMS BUBBLES. BOILING WATER- INSIDE THE WATER THE BUBBLES ARE VAPOR, THIS HAPPENS AT THE GREATEST RATE DURING THE BOILING POINT COMING OFF THE TOP OF THE WATER IS EVAPORATION

VAPORIZATION PHASE CHANGE FROM LIQUID TO VAPOR

SUBLIMATION THE ROOT WORD IS SUBLIME CHEMISTRY DEFINITION IS DIFFERENT THAT REAL WORLD DEFINITION WHEN A SOLID CHANGES DIRECTLY TO A GAS

PHYSICAL PROPERTIES VS. CHEMICAL PROPERTIES PHYSICAL PROPERTIES NO CHANGE IN THE ATOMS OR PARTICLES COLOR, SMELL, LUSTER CONDUCTIVITY (ELECTRICITY) FREEZING, BOILING, AND MELTING POINTS VISCOSITY DENSITY BREAKING, BENDING (MALLEABILITY) CHEMICAL PROPERTIES CHANGE IN THE PARTICLES FORMING A NEW SUBSTANCE RUSTING (REACTIVITY) BURNING (FLAMMABILITY) pH

LAST SLIDE (BONUS) WHAT IS A PURE SUBSTANCE? AN ELEMENT BECAUSE IT IS MADE UP OF ALL ONE ATOM- THERE IS NOT ANY OTHER ATOMS OR PARTICLES WITH IT.
