what changes because of independent variable 

mass of particles..... arrangement of particle....... movement of particles 

closely spaced...... held in fixed position but vibrates......... regular arrangement............... cannot compress solid

closely spaced...... particles move over eachother ......... no fixed arrangement............... cannot compress liquid

widely spaced...... particles move random speed random direction ......... random arrangement............... can compress gas

solid to liquid is heating...... liquid to gas is boiling..... solid to gas is sublimation............ gas to liquid is condensation...... liquid to solid is freezing.......... gas to solid is deposition

the movement of a substance of high concentration to lower concentration

state of matter- gases diffuse either than liquid as they can spread out more quicker than liquid particle s........... temperature -hotter gas or liquid faster particles and faster diffusion...... mass of particles- smallest gas particles diffuse faster

the frequency of collision and pressure increases

what happens when temperature of gas increases

hot objects increase as they heat. space between particles increase NOT particles 

substance made of mor than one type of particles types

solid which dissolves in solvent is..... 

mass of substance that dissolves in 100ml of water. It changes with temperature 

solution with only small amount of dissolved solute

solute with large amount of dissolved solute

how can insoluble substance be separated from their substance 

how can soluble substance be separated from their substance 

some pigments r more soluble than others pigment with higher solubility move up the paper
