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.
