Concept:

Problem: Aluminum has a specific heat capacity of 0.9 J/g°C and water has a specific heat capacity of 4.2 J/g°C. How much energy is transferred from a piece of hot aluminum that is dropped in a calorimeter containing 150 g of water at 20°C if the final temperature of the water in the calorimeter is 24°C?

Thermal Equilibrium:

-q1=q2          q=mCΔT


Given:

Cs, Al = 0.9 J/g °C

ΔTalloy = 24°C – Ti


mwater = 150 g

Cs, water = 4.2 J/g °C

ΔTwater = 24°C – 20.0 °C = 4 °C
