Melanie wants to observe the effect of two new fertilizers on the growth of plants. Three identical plants having a height of 15 cm were used for the experiment. No fertilizer was added to the first plant, 100 g of Fertilizer A was added to the second plant, and 100 g of Fertilizer B was added to the third plant. All other growing conditions of the plants were kept constant. Which step of the scientific method did Melanie do here?

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.
