This is chemistry: 2 questions having to do with particles

Answer 1 :

Image 1 shows : Liquid phase

Image 2 shows : Gas phase

Image 3 shows : Solid phase

Image 4 shows : Solid phase

Solid phase : In this state, the molecules are closely and tightly packed. There is no vacant space present in it.Liquid phase : In this state, the molecules are loosely packed and there is an intermediate vacant space present in it.Gas phase : In this state, the molecules are very loosely packed and there is a lot of vacant space present in it.

Answer 2 :

Liquid to gas : Evaporation

Solid to gas : Sublimation

Gas to solid : Deposition

Solid to liquid : Melting

Liquid to solid : Freezing

Gas to liquid : Condensation

Explanation :

Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.Melting : It is a process in which a solid changes into liquid phase by providing heat.Freezing : It is a process in which a liquid transform into a solid phase.Condensation : It is a process in which a water vapor(gas) changes into liquid state.
