MATTER: Its State

Question 1

• Any substance that has mass and takes up space

- Matter includes atoms and anything made up of atoms but no other energy phenomena or waves such as light sound

Answer 1

Matter

Question 2

Answer 2

macroscopic

Question 3

elements

Question 5

groups of two or more atoms

that have been bonded together

normal temperature (0-100 C)

Answer 7

liquid

Question 8

high temperature (100 C)

Answer 8

Gas

Question 9

• Ionized Atoms (Super-heated atoms)

Answer 10

Plasma

Question 11

• A group of atoms cooled to within a hair of absolute zero
• When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so.

Answer 11

Bose-Einstein Condensate

o Exactsameconcentrations

Answer 16

homogenous mixture

Question 17

Not Uniform composition (all throughout the mixture).

Answer 17

heterogenous

Question 18

homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility

Answer 18

solutions

Question 19

a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation.

Answer 19

Question 20

any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye;

Answer 20

colloid

Question 21

mixture of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size

Answer 21

emulsions

Question 22

Those it spreads across, maximizing contact
