Matter in Any State is Composed of Particles. Compare the Three States of Matter I,E. Solids, Liquids, and Gases with Reference To: - Chemistry

Answer in Brief

Matter in any state is composed of particles. Compare the three states of matter i,e. solids, liquids, and gases with reference to:

(a) intermolecular space
(b) the intermolecular force of attraction
(c) movement of particles



Characteristics Solids Liquids Gases
Intermolecular space Minimum space More than solids Maximum space
 Intermolecular force of attraction Very strong Less strong Very weak
movement of particles About their own position In continuous motion In any random direction
  Is there an error in this question or solution?
