A group of students are studying how different stimuli affect the growth of plants. They place a growth lamp next to a plant that has been placed in a dark room. To ensure the survival of the plant the make sure to provide an adequate amount of nutrients and water. Which way is the plant most likely to respond? Wilting and ultimately dying.

Bending toward the light provided by the lamp.

Increasing the rate of photosynthesis.

Shedding all of its leaves.

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.
