The ice and ocean in the image are both forms of H2O, in its
solid and liquid states, respectively. This representation of
water written as "H2O" aligns with which domain in chemistry?
- CORRECT ANSWER-Symbolic
The representation of water using H2O is an aspect of the
symbolic domain.
The image below was captured over a hot mug of coffee on a
cold morning. Which state(s) of matter are present in the
image? - CORRECT ANSWER-Liquid & Gas
The image shows steam condensing as it hits the cool air. Pure
steam, which is in gas phase, is completely invisible. The cloudy
appearance comes from droplets of liquid water that form when
the steam cools upon mixing with the cold air.
Which of the following could be considered a chemical change?
- CORRECT ANSWER-Coal burning.
,Phase changes and mixing of substances are physical processes.
When coal burns, carbon atoms form new chemical bonds to
oxygen atoms, which is a chemical process.
A strong magnet placed under a piece of paper makes a three-
dimensional pattern in iron filings that are placed on top of the
paper. This is an example of which of the following? - CORRECT
ANSWER-Physical Change.
A physical change is a change in the state or properties of
matter without any accompanying change in chemical
composition. In the organization of the filings into a 3D form by
the magnet, there is no chemical change. Also, none of the
extensive or intensive properties of the magnet or filings
change.
Which is an extensive property? - CORRECT ANSWER-Length.
The length of a substance does depend on the quantity present,
the other examples do not.
A strong magnet placed under a piece of paper makes a three-

ANSWER-Physical change.
A physical change is a change in the state or properties of
matter without any accompanying change in chemical
composition. In the organization of the filings into a three-
,dimensional form by the magnet, there is no chemical change.
Also, none of the extensive or intensive properties of the
magnet or filings change.
Which of the following does not change if the sample size
changes? - CORRECT ANSWER-An intensive property
An intensive property does not change if the sample size
changes.
Which of the following is an example of an extensive property?
Density
Color
Odor
Mass - CORRECT ANSWER-Mass
An extensive property is dependent on the amount of matter
present. Mass is an extensive property
Which is an intensive property?
Volume
Melting point
Weight
Heat - CORRECT ANSWER-Melting point
Recall that an intensive property is a property of matter that is
independent of the amount of substance in a sample. The
, melting point of a substance is an intensive property because it
does not depend on the amount of substance present. Heat,
volume, and weight are extensive properties because they
depend on the amount of substance in a sample.
Which is an intensive property?
Mass
Shape
Length
Density - CORRECT ANSWER-Density
No matter how much of a substance is present, it will have the
same density. The other characteristics will change according to
the quantity.
Which of the following properties is dependent on the amount
of matter present?
Intensive
Extensive
Chemical
Physical - CORRECT ANSWER-Extensive
Extensive properties depend on the amount of matter present
James drops a wooden block into a tank of water and notices
that it floats. He then cuts the block in half, drops the block into
the same tank and once again the block floats. James realizes
that cutting the block in half does not change its density. What
