1a-states of matter Flashcards
what is the process of solid to gas and visa versa called?
solid to gas - sublimation
gas to solid - Deposition
What is diffusion?
the movement and mixing of particles from an area of high concentration to an area of low concentration
What is a solubility curve?
a curve that shows how the solubility of a substance (in grams per 100 g of
water) changes with temperature.
what are two facts about the kinetic theory of matter?
- Matter is made up of atoms, molecules and ions of different sizes.
- At the same temp, small particles move faster than large particles
name 4 key parts of the structure of solids
- particles are fixed in a regular arrangement
- particles are very close together
- particles vibrate
- strong forces of attraction between particles
what is melting?
when a solid turns into a liquid
which has the highest density - solids, liquids or gases?
solids
what are 4 key parts of the structure of a liquid?
- particles are arranged randomly
- particles are close together
- particles are free to move randomly
- some forces of attraction between the particles
what are 4 key parts of the structure of a gas?
- particles are randomly arranged
- particles are far apart
- particles move freely and randomly
- weak/no forces of attraction between particles
can particles in a liquid move freely?
no. they have restricted movement.
are the melting point and freezing point of a substance are the same.
yes
what is the process of gas to liquid called?
condensing
what is the process of liquid to gas called?
evaporating
