In the next experiment, scientists plan to take the same metal cube, but add 4000J of energy to heat it up from room temperature (23oC) the thermal equilibrium of the water and cube is 25 C. The metal that the cube is made of has a melting point of 450oC and a boiling point of 1280oC. What state of matter will the cube be once it is heated up? Use math to support your answer.

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.
