States Of Matter Flashcards

Q

What state something is at a certain temperature depends on what?

A

How strong the forces of attraction are between the particles of the material depend on

  1. The material (structure of substance and types of bonds)
  2. Temperature
  3. Pressure

Q

Describe 3 properties of a solid

A
  1. Strong forces of attraction between particles, holds them close together in fixed positions to form a regular lattice arrangement
  2. Particles don’t move so they kept a definite shape and volume and don’t flow
  3. Particles vibrate- hotter the solid the more it vibrates

Q

Describe 3 properties of liquid

A
  1. Weak force of attraction, randomly arranged, free to move, tend to stick closely together
  2. Definite volume but don’t keep definite shape, can flow
  3. Constantly moving with random motion, the hotter the liquid, the faster they move, causes liquid to expand when heated

Q

Describe 3 properties of gases

A
  1. Force of attraction is very weak, free to move and are far apart, the particles in gases travel in straight lines
  2. Don’t keep a definite shape or volume and will always fill containers
  3. Move in random motion, the hotter, the faster they move, pressure increases

Q

What are he limitations or particle theory

A

Reality, part makes aren’t spheres, they’re atoms, ions or molecules
They don’t show the forces between the particles, so we don’t know if they’re strong
