Explain how does the intermolecular forces of attraction among the constitute particle and Kinetic energy affect the physical state of matte
Answers
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. Increasing the pressure on a substance forces the molecules closer together, which increases the strength of intermolecular forces.
Explanation:
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.
