Strongest intermolecular forces

Hydrogen

1

Weakest

Dispersion

2

Middle

Dipole dipole

3

Dipole dipole

Attractive forces between positive end of one polar molecule and the negative end of another; permanent polar, arrow pulling towards negative

4

Dispersion

Greater dispersion force, larger molecule, weakest, no overall dipole,

5

Properties of plasma

Contains ions, same properties as gases

6

Two types of solids

Crystalline
Orderly, geometric, repeating structure, definite melting point

Amorphous
Random, no definite melting point

7

Surface tension

Measure of inward pull

8

Capillary action

Wicking

9

What affects viscosity?

Attractive forces
Particles size and shape
Temperature

10

In the KMT the gases are assumed to be

Ideal

11

6 Assumptions of KMT

1) gases consist of tiny particles
2) distance between particles is large compared to particle size
3) gas particles have no attractive forces for one another
4) gas particles move in straight lines when they collide
5) no energy is lost during collisions (perfectly elastic)
6) the average kinetic energy is the same for all gases at the same temperature

12

Diffusion

Movement of one material through another

Gases mixing together

13

Effusion

Gas escaping through tiny opening

14

Pressure

Force per unit area

15

SI unit of force

Newton

16

Newton per meter squared

Pascal

17

Atm stands for

Atmosphere

18

Who invented the barometer and what does it do?

Torricelli and it measures atmospheric air pressure

19

Manometers

Measure gas pressure in closed container

Open vs closed

20

Partial pressure is independent of the type of gas and depends on

Moles, size of container, temperature

21

What is stronger intra or inter?

Intra

22

Intermolecular force that exists between all particles

Dispersion

23

Hydrogen bonds occur between

Fluorine, oxygen, nitrogen

24

Vaporization only at the surface of a liquid

Evaporation

25

Point where the difference from liquid and vapor are indistinguishable

Critical point I

26

Point of the phase diagram that represents the temp and pressure at which all 3 phases coexist

Triple point

27

Reverse of sublimation

Deposition

28

If something has no dipole, it's being pulled equally which means it's ___

Nonpolar

29

Water is a ____with ___lone pairs

Bent
Two
