Question

describe the motion and attraction of molecules during sublimation​

Answer 1

Answer:

Sublimation is caused by the absorption of heat which provides enough energy for some molecules to overcome the attractive forces of their neighbors and escape into the vapor phase. Since the process requires additional energy, it is an endothermic change. When energy is transferred to dry ice, the solid carbon dioxide does not melt to liquid carbon dioxide. Instead, the solid changes directly to a gas. This process is called sublimation. Sublimation occurs when molecules of a solid move fast enough to overcome the attractions from other molecules and become a gas.
