1. A 50g block of aluminum at-100°C is submerged in 30g of water at 20°C. Cwater = 4.184 J/gºC
CA = 0.89 J/gºC
AHrus water = 334 J/g
a. What is the final temperature of both substances?
b. How much energy is gained by the block of aluminum?

Analyze how limestone is weathered and identify the features that are formed as a result of this dissolution

How does the motion of particles in a gas change as the gas cools

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.
