Question

Explain in detail how does the competition between inter molecular forces of attraction among the constituent particles and their kinetic energy affect the physical state of matter.

Answer 1

• As kinetic energy increases with the increase in temperature the particles of matter are able to move more freely.
• Due to their ability to move freely, the intermolecular forces of attraction become weak and so the physical state changes.
• If the intermolecular force of attraction is higher than the kinetic energy then the physical state will be of liquid or solid state.
• If the kinetic energy is greater than the intermolecular force of attraction then the physical state should be gas as molecules collide with each other randomly.
