Which is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas? Particle spacing can allow a very high density. Particle kinetic energy is independent of temperature. Particles vibrate quickly in stationary positions. Particles exchange energy through elastic collisions.

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.
