During which changes of state do atoms overcome the attractive forces between them? freezing and condensation boiling and deposition condensation and melting vaporization and sublimation

really dont know just need some points

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
