Vedclass · Answer

(A) The physical state of matter (solid,liquid,or gas) is determined by the kinetic energy of its particles and the intermolecular forces of attraction.To change the physical state,one must either increase the kinetic energy (by heating/supplying energy) to overcome intermolecular forces or decrease the kinetic energy (by cooling/removing energy) to allow particles to come closer.Therefore,a change in physical state requires an exchange of energy with the surroundings,either by adding or removing it.

$A$ change in the physical state of matter can be brought about:
