Explanation:
There are 3 states of matter:
Solid state: In this state of matter, the particles are closely packed and they do not have any space between them. Thus, this state of matter has the highest intermolecular forces of attraction between them.
The kinetic energy of the solid particles is the least.
Liquid state: In this state of matter, the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. The intermolecular forces between the particles are less as compared to the solid state.
The kinetic energy of the liquid particles lie in the intermediate of solid and gases.
Gaseous state: In this state, the particles are loosely arranged and have a lot of space between them. Thus, this state of matter has the lowest intermolecular forces of attraction between them.
The kinetic energy of the gaseous particles is the highest.
- Conversion of solid to liquid:
The spacing between the particles increases and so does the kinetic energy. The particles which were closely packed, on getting converted to liquid particles are now present in random and irregular pattern.
- Conversion of liquid to gas:
The spacing between the particles increases and so does the kinetic energy. The particles which were present in irregular pattern, on getting converted to gas particles are now loosely arranged.
The space between the particles grows and energy increases as they change from solid to liquid and decrease from gas to liquid.
Physical state
The physical state of a substance depends on the organization of its molecules.
If they are closer together, we have the solid state, if they are a little apart, you have the liquid state, and if they are further apart, we have the gaseous state.
Thus, when it changes from a solid to a liquid it increases this distance and when it changes from a gas to a liquid it decreases this distance.
Energy
In addition, the energy of the system also increases with increasing distance.
So from solid to liquid this energy would increase and gas to liquid this energy would decrease.
