Question

During which changes of state do atoms overcome the attractive forces between them?

Answer 1

Atoms overcome the attractive forces between them through vaporization and sublimation .in vaporization the atoms are from gas to liquid while in sublimation it is from solid to gas which skips liquid state.through this the attractive force of the atoms does not meet in the liquid state because sublimation does not undergo in liquid phase. hope this help

Answer 2

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.
