Problem: A copper cube with an edge measuring 1.57 cm and an aluminum cube with an edge measuring 1.66 cm are both heated to 57.6 oC and submerged in 100.0 mL of water at 21.9 oC.What is the final temperature of the water when equilibrium is reached? (Assume a density of 0.998 g/mL for water.) 

🤓 Based on our data, we think this question is relevant for Professor Richert's class at ASU.

Concept: Calorimetry with Thermal Equilibrium

What we will need:

• Density of Copper = 8.96 g/cm3             

• Density of Aluminum = 2.7 g/cm3

• Density of water = 0.998 g/mL  (given)

We also need to find masses of both metals and water. To do that we will use density and volume of each.
