The four fundamental forces are arranged in the increasing order of their relative strength. (A, B and C represent three of the fundamental forces.)
Gravity Which statement is true about the fundamental forces represented by A and C?
O Both have infinite range.
Both act only between charged particles.
O Both act only between non-atomic particles.
Both are experienced by atoms and subatomic particles

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.
