Question

During which changes of state do atoms overcome the attractive forces between them

Answer 1

Answer: Melting, vaporization and sublimation.

Explanation: Melting is a process in which solid phase changes to liquid phase by absorbing heat and thus the particle atoms overcome the attractive forces between solids and move away from each other in liquids. The reverse process is freezing in which particles come close to each other.

$Solid\rightleftharpoons liquid$

Vaporization is a process in which liquid phase changes to gaseous phase by absorbing heat and thus the particle atoms overcome the attractive forces between liquids and move away from each other in gaseous phase.The reverse process is condensation in which particles come close to each other.

$Liquid\rightleftharpoons Gas$

Sublimation is is a process in which solid phase directly changes to gaseous phase by absorbing heat and thus the particle atoms overcome the attractive forces between solids and move away from each other in gaseous phase.The reverse process is deposition in which particles come close to each other.

$Solid\rightleftharpoons Gas$

Answer 2

The correct answer is D. Vaporation and Sublimation. The changes of state that atoms overcome the attractive forces between them is during evaporation and sublimation. The changes of state when the motions of atoms decreases is during freezing and condensation. Hope this helps :)
