Cards

Term
WHAT IS A SOLID ?
Definition
DEFINITE (EXACT)SHAPE AND DEFINITE VOLUME .
Term
HOW DO THE PARTICLES OF A SOLID WORK ?
Definition
PACKED TIGHTLY TOGETHER AND EACH PARTICLE IS SET IN ONE POSITION .
Term
HOW DO THE PARTICLES OF A SOLID'S MOVEMENT WORK ?
Definition
THEIR MOVEMENT IS SMALL , AND THEY CAN ONLY VIBRATE .
Term
SOLID 1 - CRYSTALLINE IS ?
Definition
SOLIDS THAT ARE FORMED WITH REGULAR PARTICLE PATTERN .
Term
SOLID 2 -AMORPHOUS IS ?
Definition
SOLIDS THAT FORM NO REGULAR PATTERN OR DOESN'T MELT AT DISTINCT TEMPERATURE .
Term
DO SOLID PARTICLES MOVE ?
Definition
THEY DON'T MOVE THEY ONLY VIBRATE
Term
WHAT'S PARTICLES IN A LIQUID ?
Definition
LIQUID PARTICLES CAN COLLIDE AND MOVE PAST ONE ANOTHER .
Term
WHAT IS A LIQUID PARTICLE ?
Definition
HAVE MORE AMOUNT OF MOVEMENT THAN SOLIDS
Term
WHAT'S A FLUID ?
Definition
SUBSTANCE THAT FLOWS , LIQUIDS ARE FLUIDS.
Term
WHAT'S VOLUME ?
Definition
LENGTH * WIDTH * HEIGHT
Term
EXPLAIN HOW A LIQUID WORKS ?
Definition
HAS DEFINITE VOLUME BUT NO SHAPE OF ITS OWN . LIQUIDS ARE JUST SOLIDS THAT HAVE DEFINITE VOLUME .
Term
WHAT IS A SURFACE TENSION ?
Definition
AN INWARD PULL AMONG MOLECULES OF A LIQUID THAT BRINGS THE MOLECULES ON THE SURFACE CLOSER TOGETHER.
Term
EXPLAIN THE DEFINITION OF GASES
Definition
CAN CHANGE VOLUME VERY EASILY , NO DEFINITE SHAPE OR VOLUME . GAS PARTICLES COLLIDE FREQUENTLY AND FREE TO MOVE INDEPENDENTLY.
Term
EXPLAIN STATES OF MATTER ?
Definition
DEPEND ON MOLECULAR MOTION. MATTER CHANGES WHEN THERMAL ENERGY IS ADDED OR SUBTRACTED.
Term
WHAT HAPPENS WHEN SOLIDS BECOME LIQUIDS ?
Definition
THEY MOVE FASTER AND FASTER THEN THEY BREAK FREE FROM THEIR FIXED POSITIONS . SOLID CHANGES TO LIQUID = MELTING .
Term
WHAT IS MELTING POINT ?
Definition
A CERTAIN TEMPERATURE THAT WILL CAUSE A SOLIDS PARTICLES TO BREAK FREE .
Term
WHAT HAPPENS WHEN A SUBSTANCE FREEZES ?
Definition
THE PARTICLES IN A LIQUID MOVE SO SLOWLY THAT THEY BEGIN TO TAKE ON A FIXED POSITION , OR BECOMING A SOLID .
Term
WHAT IS VAPORIZATION ?
Definition
IT HAPPENS WHEN THE PARTICLES IN A LIQUID GAIN ENOUGH ENERGY TO MOVE INDEPENDENTLY FORMING A GAS .
Term
VAPORIZATION 1 - WHAT'S EVAPORATION ?
Definition
WHEN A LIQUID VAPORIZES ONLY ON TOP OF A SURFACE ON A LIQUID .
Term
VAPORIZATION 2 - EXPLAIN BOILING
Definition
WHEN A LIQUID CHANGES INTO A GAS FROM BELOW AND ON THE SURFACE
Term
WHATS BOILING POINT ?
Definition
THE TEMPERATURE AT WHICH LIQUID BOILS
Term
WHAT IS CONDENSATION ?
Definition
THE CHANGE IN STATE FROM A GAS TO A LIQUID
Term
WHATS SUBLIMATION
Definition
OCCURS WHEN THE SURFACE PARTICLES OF A SOLID GAIN ENOUGH ENERGY THAT FORM A GAS
Term
WHATS VOLUME ?
Definition
AMOUNT OF SPACE THAT MATTER TAKES UP AND IS MEASURE IN CUBIC CENTEMETERS
Term
WHATS TEMPERATURE ?
Definition
MEASURE OF AVERAGE ENERGY MOTION OF PARTICLES OF MATTER
Term
WHAT IS PRESSURE ?
Definition
THE FORCE OF OUTWARD PUSH DIVIDED BY AREA OF WALLS OF CONTAINER
Term
EXPLAIN CHARLES LAW !
Definition
WHEN TEMPERATURE GOES UP , VOLUME GOES UP AS WELL
Term
WHAT IS BOYLE'S LAW !
Definition
WHEN PRESSURE GOES UP , VOLUME GOES DOWN
