Which has more interparticle force of attraction ?Solid form of ice or in its vapour state ?
Answers
Solid form of ice will have more inter particle/ inter molecular force of attraction.
Hope it helped! :)
Answer:
The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance and the intermolecular forces try to draw the particles together.
gases
average kinetic energy of the molecules is larger than average energy of attractions between molecules
lack of strong attractive forces allows gases to expand
liquids
denser than gases
have a definite volume
attractive forces not strong enough to keep molecules from moving allowing liquids to hold shape of container
solids
intermolecular forces hold molecules together and keep them from moving
not very compressible
crystalline – solids with highly ordered structures
Gas
assumes both the volume and shape of container is compressible diffusion within a gas occurs rapidly flows readily
Liquid
Assumes the shape of the portion of the container it occupies Does not expand to fill container Is virtually incompressible Diffusion within a liquid occurs slowly Flows readily
Solid
Retains its own shape and volume Is virtually incompressible Diffusion within a solid occurs extremely slowly Does not flow
state of substance depends on balance between the kinetic energies of the particles and interparticle energies of attraction
kinetic energies depends on temperature and tend to keep particles apart and moving
interparticle attractions draw particles together
condensed phases – liquids and solids because particles are close together compared to gases
increase temperature forces molecules to be closer together ® increase in strength of intermolecular forces
