<u>Answer:</u>
The correct answer option is a) collisions between the particles and surrounding molecules.
<u>Explanation:</u>
The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.
Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.
It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.
Answer:
Freezing
Melting
Condensation
Evaporation
Sublimation
Deposition
Explanation:
From the diagram,
(1) Liquid⇒Solid (Freezing)
Freezing: This is the process by through which a substance change from liquid to solid.
(2) Solid⇒Liquid (Melting)
Melting: This is a process through which a substance change from solid to liquid
(3) Liquid⇒gas (Evaporation)
Evaporation: This is a process through which a substance change from liquid to gas.
(4) gas⇒Liquid (Condensation)
Condensation: This is a process through which a substance change from gas to liquid
(5) Solid⇒gas (Sublimation)
Sublimation: this is a process through which a subtance change from solid to gas
(6) gas⇒solid (Deposition)
Deposition: This is a process through which gas transform into solid.
