What are the four states of matter

Solid liquid gas plasma

1

What are three parts of kinetic molecular theory

1) all particles in random motion
2) particles are colliding with walls and other molecules
3) they don't lose energy with collisions

2

Measures atmospheric pressure

Barometer

3

Measures pressure in the system

Manometer

4

Caused by collisions of gas particles with a surface

Pressure

5

Movement from high to low concentration

Diffusion

6

What is Grahams law of diffusion

The smaller the molecule the faster they spread out

7

What Does Dalton's law of partial pressures state

The total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture

8

Bonds within a molecule

Intramolecular forces

9

Forces between separate molecules

Intermolecular forces

10

Week forces that result from temporary shifts in the density of electrons in electron clouds

Dispersion forces

11

Attractions between oppositely charged regions of polar molecules

Dipole dipole forces

12

Is a dipole dipole attraction that occurs between molecules containing a hydrogen atom bonded to a small electronegative Atom

Hydrogen bond

13

Resistance to flow

Viscosity

14

A measure of the inward pool by particles in the interior

Surface tension

15

A force between two of the same molecules

Cohesion

16

Force between different types of molecules

Adhesion

17

Compounds that lower the surface tension of water

Surfactants

18

A solid whose Atoms ions or molecules are arranged in an orderly geometric structure

Crystalline solid

19

The smallest arrangement of atoms in a crystal lattice that has the same symmetry as the whole crystal

Unit cell

20

Random structure

Amorphous

21

an element that exists in different forms at the same state

Allotrope

22

Process by which a liquid changes to a gas

Vaporization

23

When vaporization occurs only at the surface of a liquid

Evaporation

24

Pressure exerted by a vapor over a liquid

Vapor pressure

25

Process by which a gas becomes a liquid

Condensation

26

Process by which a substance changes from gas to sell it

Deposition

27

This point represents the temperature and pressure at which three phases of a substance can coexist

Triple point
