Question

during sublimation , the intermolecular interactions is​

Answer 1

Answer:

Sublimation is the change of state in which a solid changes directly into a gas. A. Losing or Gaining Energy When most substances lose or gain energy, one of two things happens to the substance: its temperature changes or its state changes.

The process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Solid carbon dioxide changes directly to the gaseous state.

• Eg. "Dry ice" or solid carbon dioxide sublimes.

• Snow and ice can sublime in the winter months without melting.

• Moth balls sublime.

• Frozen foods will sublime and you will find ice crystals inside of the box or bag.

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.
