6.4 Heat Capacity and Calorimetry
BeginnerMCQProportional AnalysisConceptual15.3k
A student conducts a calorimetry experiment in which a sample of solid aluminum and a sample of liquid water, each with a mass of \(50.0\text{ g}\) and initially at \(20.0\ ^\circ\text{C}\), each absorb \(1.00 \times 10^3\text{ J}\) of thermal energy under conditions where no phase changes occur. The specific heat capacity of liquid water is \(4.18\text{ J}/(\text{g}\cdot^\circ\text{C})\) and the specific heat capacity of aluminum is \(0.90\text{ J}/(\text{g}\cdot^\circ\text{C})\). Which of the following correctly compares the final temperature of aluminum, \(T_{\text{final, Al}}\), to the final temperature of water, \(T_{\text{final, water}}\), and provides the correct justification?
