Three grams of the same substance in different phases are stored in three different containers. Each containers. is barley large enough to hold the substance. Which statement can be known about the behavior of the atoms in each container?

The atoms in the solid would be moving vigorously around the container
The atoms in the liquid would be vibrating in position
The atoms in the solid would be vibrating in position
The atoms in the gas would be moving slowly around the container

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.
