colloid
A mixture containing small, undissolved particles that do not settle.
suspension
A mixture in which particles can be seen and easily separated by settling or filtration
homogen
A mixture in which substances are evenly distributed throughout the mixture, homogeneous mixtures appear uniform throughout.
heterogeneous mixture

physical property
