Which arrow represents the change of state described above? The diagram shows changes of state between sold, liquid, and gas. The atoms of a substance lose energy during a change of state. After the change, the atoms are close together but are able to slide past one another. Which represents the change of state described above?

May someone me with these science questions

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
