Chapter 3 Section 1

Question 1

states of matter

Answer 1

the physical forms in which a subject can exist

Question 2

solid

Answer 2

the state in which matter has a definite shape and volume

Question 3

two categories of solids

Answer 3

crystalline and amorphous

Question 4

liquid

Answer 4

state in which matter takes the shape of its container and has a definite volume

Question 5

surface tension

Answer 5

the force acting on the particles at the surface of a liquid that cause the liquid to form spherical drops

Question 6

viscosity

Answer 6

a liquid’s resistance to flow

Question 7

gas

Answer 7

the state in which matter changes in both shape and volume

Question 8

pressure

Answer 8

amount of force exerted on a given area

Question 9

Boyle’s Law

Answer 9

for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases

Question 10

Charles’s Law

Answer 10

for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature increases

Question 11

plasma

Answer 11

state of matter that does not have a definite shape or volume and whose particles have broken apart.

Question 12

examples of a crystalline solid

Answer 12

diamonds, ice, and iron

Question 13

examples of an amorphous solid

Answer 13

rubber and wax

Question 14

how the particles of a gas move

Answer 14

They move fast enough to overcome nearly all of the attraction between them.

Question 15

how the particles of a solid move

Answer 15

they do NOT move fast enough to overcome any of the attraction between them

Question 16

how the particles of a liquid move

Answer 16

they move fast enough to overcome SOME of the attraction between them

Question 17
