If 10.0 g of copper was heated from 10.0°C to 80.0°C, how much energy was used to heat Cu? The specific heat capacity of Cu is 0.092 cal/g °C.

Define dew point. i am writing this part to be able to ask the question

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

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.
