Answer 9

Plasma

Question 10

The characteristics of _________ are significantly different from those of ordinary neutral gases that _________ are considered a distinct “fourth state of matter.”

Answer 10

Plasma, plasmas

Question 11

It is a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero

Answer 11

BOSE-EINSTEIN CONDENSATE

Question 12

When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. At that point, the atoms begin to clump together, and enter the same energy states.

Answer 12

BOSE-EINSTEIN CONDENSATE

Question 13

Question 14

These can be measured and observed without changing the composition of the substance

Answer 14

PHYSICAL PROPERTIES

Question 15

These are the ability of a substance to react with other substances such as air, water, and base.

Answer 15

CHEMICAL PROPERTIES

Question 16

It does not depend on the size or amount of the sample.

Answer 16

INTENSIVE PROPERTIES

Question 17

These can be affected by the size and amount of samples.

Answer 17

EXTENSIVE PROPERTIES

Question 18

List of Intensive Physical Properties

Question 20

(Chemical Properties)
Whether the substance undergoes combustion or not

Answer 20

Combustibility

Question 21

(Chemical Properties)
Whether the substance can be easily decomposed or not

Answer 21

Stability

Question 22

(Chemical Properties)
Whether it reacts with acids, bases, and oxygen, gas or not

Answer 22

Reactivity

Question 23

(Chemical Properties)
Whether the material is more active or less active than other members of its chemical family

Answer 23

Relative Activity

Question 24

(Chemical Properties)

Answer 24

fonization

Question 25

(Chemical Properties) Whether substance can damage an organism or not.

Answer 25

Toxicity

Question 26

WHAT IS MATTER?

Answer 26

Makes up the matter. Is defined as anything that occupies space and has mass

Question 27

__________ describe by its properties. But a single characteristics may not be enough to identify __________.

Answer 27

Matter

Question 28

Why isn't it a good idea to classify matter by its phases?

Answer 28

Because one kind of substance can exist in more than one phase - such as H20. And matter changes phases rather easily.

Question 29

Why isn't matter classified according to its physical characteristics, such as color?

Answer 29

Scientists wouldn't find it very useful to group gold, sunflowers, and the sun together

Question 30

Scientist look for _________ and _________ properties to help identify anything conclusively

Answer 30

Physical and Chemical

Question 31

One way that scientists classify matter is by its ________.

Answer 31

composition

Question 32

Ultimately, all matter can be classified as _____________ or _________-.

Answer 32

pure substance, or mixture

Question 33

Scientists ask themselves these questions? [4]

Answer 33

•Is the matter uniform throughout? •Can it be separated by physical means? •Can it be separated by chemical means?
