Let's think! Comparing the containers A and B, you can see if there are differences? What do you call each portion you observe? How have solid container A and how many phases it presents? How many components are in the container B? The components A and B are homogeneous or heterogeneous mixtures? Mayonnaise container C is a system homogeneous or heterogeneous? The container has many components D? What is the number of stages? The mixtures are also classified according to the average size of the dispersed particles. To measure the particle size are usually used two different units: the angstrorn ( ) and nanometer (nm). m 1 nm = 10 m 1nm = 10A As the average size of the dispersed particles, dispersions are classified into solutions colloidal dispersions and suspensions You could tell that the resemblance between the refreshment, gelatin and mud? Let's find out? Mud (or clay) is a heterogeneous mixture or suspension that has two or more stages and whose dispersed phase is formed by solid particles with an average diameter greater than 100nm. If the dispersed has higher density than the dispergente he can sedimentary (deposited) spontaneously.

Razmislimo! Uspoređujući s posudama A i B, što možete vidjeti postoje li razlike? Kako zoveš svaki dio li promatrati? Kako su čvrste kontejner i koliko faze ona predstavlja? Koliko dijelovi su u kontejner B? Komponente A i B su homogene ili heterogene smjese? Majoneze kontejner C je sustav homogene ili heterogene? Kontejner ima puno komponenti D? Što je broj stupnjeva? Smjese su podijeljena s prosječnom veličine raspršenih čestica. Za mjerenje veličine čestica obično koriste dvije različite cjeline: angstrorn ( ), a nanometar (nm). m 1 nm = 10 m 1nm = 10A Kao prosječne veličine raspršenih čestica, disperzije su razvrstani u rješenjima koloidne disperzije suspenzija Ti bi mogao reći da je sličnost između osvježenje, želatina i blata? Otkrijmo? Mulj (ili gline) je heterogena smjesa ili ovjes koji ima dvije ili više faza i čije raspršeni faza je formirana čvrstih čestica s prosječnim promjerom većim od 100nm. Ako raspršili ima veću gustoću nego dispergente on može sedimentne (deponiran) spontano.
