Consider the air in the entire system (syringe, rubber hose, rubber stopper and metal can). As the air in the system reaches thermal equilibrium with the cool water, describe how each of the following changes (if at all). Wherever possible, explain your answers in terms of changes to the individual molecules of air that produces the macroscopic changes. Volume: Pressure: Temperature: Number of air molecules: Internal energy of the gas:
