1. a - States of matter Flashcards
describe a solid in terms of
arrangement
strong forces of attraction
close together
fixed position
regular lattice arrangement
describe a solid in terms of
movement
don’t move
keep a definite shape and volume
describe a solid in terms of
energy of particles
vibrate about their positions
hotter = vibrate more ( solids expand slightly when heated )
describe a liquid in terms of
arrangement
weak force of attraction
randomly arranged
free to move past each
stick closely together
describe a liquid in terms of
movement
free to move past each other
definite volume
don’t keep a definite shape
describe a liquid in terms of
energy of particles
constantly moving
random motion
hotter = move faster ( liquids expand slightly when heated )
describe a gas in terms of
arrangement
very weak force of attraction
free to move
far apart
gas particles travel in straight lines
describe a gas in terms of
movement
don’t keep a definite shape
don’t keep a definite volume
fill any container
describe a gas in terms of
energy of particles
move constantly
random motion
hotter= move faster ( expand or pressure increases when heated )
name of process of solid to liquid
+ explain changes
melting
particles enough energy to break free from positions
name of process of liquid to solid
freezing
name of process of liquid to gas
+ explain changes
evaporating
particle enough energy to break their bonds
name of process of gas to liquid
condensing
name of process of solid to gas + gas to solid
subliming
definition of dilution
??? process of reducing the concentration of a solute in solution simply by mixing with more solvent
