Flashcards in States Of Matter And The Kinetic Motion Theory Deck (18):
1

What does Brownian Motion state?

All substances consist of small particles constantly in motion

2

Name the 3 states of matter and what they depend on?

Solid, liquid, gas
•kinetic energy of the particles
• intermolecular forces

3

What is temperature?

Measure of the particles average kinetic energy(higher the temp ; faster the particles move)

4

Solid to liquid?

Melting

5

Liquid to gas?

Boiling

6

Gas to liquid

Condensation

7

Liquid to solid

Freezing

8

Solid to gas

Sublimation

9

Gas to solid

Deposition

10

What does the kinetic molecular theory explain?

The movement of particles(spacing,order,motion)

11

Properties of solids?

Fixed positions
Strong IMF
High particle density
Particles vibrate in fixed positions
Not easily compressible

12

Liquids

Particles move over each other
Weaker IMF
Lower particle density
Particles move vigorously
Not easily compressible
Exert pressure on all side of the container

13

Gases?

Particles far apart
Almost no IMF
Low particle density
Particles move quickly
Compressible
Collision of particles exerts pressure

14

Explain what happens when while heating a solid?

Temp increase, average kinetic energy increases, particles vibrate faster, IMF are very strong, particles are tightly packed in a fixed order called a lattice structure.

15

Explain phase change solid~>liquid

Solid-> liquid, constant temp, average kinetic energy is constant, heat is absorbed by the particles to overcome the IMF, strength of the IMF starts decreasing

16

Describe what happens while heating a liquid

Temp increases, avg kinetic energy increase, particle move faster, IMF are weaker, particles move more freely, bigger intermolecular spaces

17

Phase change: liquid to gas

Liquid->gas. Constant temp, constant avg kinetic energy, heat absorbed by particles to over come IMF, decreasing strength of IMF more

18

Explain what happens while heating a gas?

Temp inc. avg kinetic energy inc, particle smoke vigorously, IMF very weak, particles move freely with large spaces
