Determine the final temperature of a 200. mL glass of water starting at 25.0°C after you placed one 20.0 g piece of aluminum into the water from your -20.0°C freezer. Assume the only heat exchange is among the aluminum and the water and determines your final temperature in the °C.
The molar mass of aluminum is 26.98 g· mol-, the molar heat capacity of aluminum is 12.5 J·K-1·mol-1, the molar mass of water is 18.01 g·mol-1 and the density of aluminum is 2.70g·cm-3.
