-dust in the air -smells from cooking
placing crystal purple potassium magnate in water and it will dissolve -place 2 open glass jars ontop of each other one with bromine and colour will spread
-atoms -molecules -ions
the smallest particle
two or more atoms joined together
atoms with a charge
regular pattern or lattice only movements are vibrations
close together not lattice can move side to side
far apart collide with eachother
the pressure exuded by particles when they collide with the walls of a container
heated gas leads to increase in pressure and decrease in volume
there is a decrease in pressure and increase in volume
-soak cotton wool in acid to give off acids gas - gases diffuse and form a smoke when they met
the lower the relative mass of an atom the faster the gas will diffuse
