An 8.4 g ice cube is placed into 260 g of water. Calculate the temperature change in the water upon the complete melting of the ice. Assume that all of the energy required to melt the ice comes from the water. Express your answer in terms of the initial temperature of water, T. a. -0.033T - 2.6 °Cb. -2.6T + 0.033 °Cc. 0.033T - 2.6 °Cd. 2.6T -0.033 °C

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

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.
