Answer : The states in which atoms overcome the attractive forces between them are melting, evaporation and sublimation process.
Explanation :
Solid state : It is a state in which the particles are closely packed and does not have any space between them. The intermolecular force of attraction between the particles are more.
Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged. The intermolecular force of attraction between the particles are lower than solid.
Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. The intermolecular force of attraction between the particles are very low.
The order of state in which atoms overcome the attractive forces between them are:
Solid state < Liquid state < Gaseous state
Thus, there are three states in which atoms overcome the attractive forces between them. The three states are:
Melting or fusion : It is a type of process in which the phase changes from solid state to liquid state at constant temperature. That means, as we are move from solid state to liquid state the attractive forces are reduces.
Evaporation : It is a type of process in which the phase changes from liquid state to gaseous state at constant temperature. That means, as we are move from liquid state to gaseous state the attractive forces are reduces.
Sublimation : It is a type of process in which the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature. That means, as we are move from solid state to gaseous state the attractive forces are reduces.
Hence, states in which atoms overcome the attractive forces between them are melting, evaporation and sublimation process.
