WHAT ARE THE THREE MAIN STATES OF MATTER?
SOLID,LIQUID,GAS
WHAT IS AN ELEMENT?
A PURE SUBSTANCE MADE OF ONLY ONE TYPE OF ATOM.
WHAT IS A HOMOGENEOUS?
A MIXTURE THAT LOOKS THE SAME.
WHAT IS CHEMICAL CHANGE?
A CHANGE THAT PRODUCES A NEW SUBSTANCE.
What are the two things that make something matter?
It has mass and takes up space.
WHICH STATE OF MATTER SPREADS OUT AND FILLS ITS CONTAINER?

WHAT IS A COMPOUND?
A SUBSTANCE MADE OF TWO OR MORE ELEMENTS CHEMICALLY COMBINED.
WHAT IS A HETEROGENEOUS MIXTURE?
A MIXTURE IN WHICH DIFFERENT PARTS CAN BE SEEN.
WHATIS A PHYSICAL CHANGE?
A CHANGE IN FORM OR STATE WHERE THE SUBSTANCE REMAINS THE SAME.
Give two examples of things that are NOT matter
Light, Sound, Energy
HOW DO PARTICLES MOVE IN LIQUID

WHAT IS CHEMICAL PROPERTY?
A PROPERTY DESCRIBING HOW A SUBSTANCE REACTS TO FORM NEW SUBSTANCES.
WHY IS MELTING ICE A PHYSICAL CHANGE?
THE WATER REMAINS WATER EVEN THOUGH ITS STATE CHANGES.
What is Volume?

GIVE ONE EXAMPLE OF A COMPOUND?
H2O, CO2, NaCI
WHAT IS PHYSCIAL PROPERTY?
A CHARACTERISTICS OBSERVED OR MEASURED WITHOUT CHANGING THE SUBSTANCE.
A STUDENT CUTS A PIECE OF PAPER INTO SMALLER PIECES. IS IT PHYSICAL OR CHEMICAL CHANGE? EXPLAIN!!
PHYSICAL CHANGE BECAUSE THE PAPER IS STILL PAPER.
What is the formula for density?
Density=Mass Volume
What can cause matter to change states?
HEAT OR COLD
WHAT IS THE DIFFERENCE BETWEEN AN ELEMENT AND A COMPOUND?
AN ELEMENT HAS ONE TYPE OF ATOM: A COMPOUND HAS TWO OR MORE ELEMENTS CHEMICALLY COMBINED.
WHAT IS THE MAIN DIFFERENCE BETWEEN HOMOGENEOUS AND HETEROGENEOUS MIXTURES?
HOMOGENEOUS LOOKS THE SAME THROUGHOUT; HETEROGENOUS HAS VISIBLE DIFFERENT PARTS.
WHAT HAPPENS TO MATTER WHEN A SUBSTANCE BURNS?
MATTER IS REARRANGED INTO NEW SUBSTANCES; IT IS NOT SIMPLY DESTROYED.
