Phenomenon 4: There is a city in Minnesota that gets extremely cold temperatures. It is the second coldest
place in the United States. The coldest temperature the city has reached is -43°C. It is no
wonder that the city has been nicknamed "The Icebox of the Nation." One day, a resident of
the city walks outside and observes one of his windows is covered in frost. He wonders about
the science behind how the frost formed. Can you explain it to him?

How can carbon move from "land" to bodies of water? describe the way human impact has lead to increased levels of co2 in the atmosphere.

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.
