A student heats a piece of aluminum, with specific heat 0.900 J/gºC, in
a large beaker of boiling water until the aluminum is 100°C. The mass
of this particular piece of aluminum is 5 grams.
If the student places the 5-g piece of aluminum in an insulated
styrofoam cup with 150 mL (150 grams) of water at room
temperature (23ºC), what is the final temperature of the aluminum
and this water going to be? Assume that we can neglect the heat
capacity of the styrofoam cup and thermometer.
