Vapour pressure
The pressure exerted by the papers of a liquid when they are in equilibrium with a liquid and vapor the process in which the rate of formation of vapour liquid and liquid from vapor is called liquid vapour equilibrium vapour pressure is directly proportional to atmospheric temperature.

 Boiling and heating. Point
The point of temperature at which a liquid starts from vapour is called its boiling point on heating the vapor pressure of a liquid becomes equal to atmospheric pressure is called boiling point of a liquid boiling point is directly proportional to atmospheric pressure

Solid State
 in solids atoms and molecules are very close to each other they are zero spaces and B towards their atoms or molecules it makes solid have a definite shape as well as volume they possess strong inter atomic are inter molecular force of attraction which makes them is strong hard or rigid state

Behavior OF Solids
Diffusion
Solids are divisible at syllabus not be it due to absence of college solid atoms and molecules according to KMT in solids atoms or molecules possess the vibration of motions on increase in temperature the vibration motion also increases which makes diffusion possible.

Comparison of compressibility
solids are not compressible due to agents of inter molecular spaces

Deformity or shuttering
When external pressure is applied over the atom of a solid they are displaced are located they are this place a dislocated this property is called as deformity according to KMT if the pressure or force is applied over the items of solid there attractive forces with other items I become weak and make them this locate from other atoms.

Melting or fusion
On heating a solid changes into liquid this call is melting or fusion

Sublimation
On heating a solid directly changes into vapors without changing into liquid is called sublimation some solids causes weaker inter molecular forces of attraction therefore on heating their attractive for sale become more week returns immediately for apart from each other to from a gas

Classification Of Solids
There Are two types of solids

  1.crystalline solids are true solids
  2. amorphic or not true solid

 crystalline solids are true solids
  do solids which possess regular geometrical shape are called as crystalline solids

Amorphic or non true solids
Do solids which do not have a regular shape are called as amorphic solids
