Silver Cluster Science Rules Matter has mass and volume
Matter is made of atoms
Matter combines to form different
substances
Different States of Matter

True or false. A compound can have very different properties than the
elements that make it up.
TRUE.
Proportions in ___________ vary; whereas proportions in __________
remain the same. A.Mixtures; CompoundsB.Compounds; Mixtures
C.Atoms; MoleculesD.Molecules; Atoms
A. Mixtures; Compounds
True or False. Most substances are considered to be pure.
False; most substances are considered to be mixed. Example:
the air you breathe.
There is more space between the particles of a _________ than there is between the particles
of a ________.
A.Liquid; GasB.Gas; LiquidC.Solid; Gas
D.Solid; Liquid
B. Gas; Liquid
True or False. When a molecule changes from one state to
another, the molecules in the substance do not change.
.
TRUE. What does
change???
Which of the following is an example of a physical molecule that you see?
A.Water moleculesB.Molecules in your desk
C.Air molecules (bouncing dust particles)D.Picture frame molecules
Both water molecules and air molecules are acceptable
How is a substance considered to be pure?
If it has only ONE type of component (molecule,
atom—ex: element)
What is a combination of different substances that remain the same individual substances and can be
separated by physical means? Please provide an example as well.
Mixture. Answers may vary—salads, trail mix,
smoothies...etc.
How is a compound different than a mixture?
A. No difference, they are the sameB. Compounds can be separated by physical means, whereas mixtures cannotC. Mixtures are separated by breaking bonds, whereas compounds are not. D. Mixtures are separated by physical means and compounds are separated by breaking bonds between atoms
D. Mixtures are separated by physical means and compounds are separated by breaking bonds between atoms.
True or False. Heterogeneous- the same throughout; homogeneous- varies
throughout .
False. Heterogeneous- varies throughout. Homogeneous- the same
throughout.
Which is NOT an example of a mixed substance?
A. paperB. airC. elementD. wood
Element—pure substance!
Whether a substance is a solid, liquid, or gas depends on how close its atoms
are to one another and...
How free the atoms are to move
True or False. Gas molecules move faster at higher
temperatures than they do at lower temperatures.
TRUE.
