A 150 g metal block (specific heat \(c_m = 0.385\,\text{J g}^{-1}\text{°C}^{-1}\)) at \(120^{\circ}\text{C}\) is placed into a calorimeter containing 200 g of water (specific heat \(c_w = 4.18\,\text{J g}^{-1}\text{°C}^{-1}\)) initially at \(25^{\circ}\text{C}\). After thermal equilibrium the temperature of the system is \(30^{\circ}\text{C}\). If the calorimeter itself has an unknown heat capacity \(C_{\text{cal}}\) (in J/°C), determine \(C_{\text{cal}}\).

Answer Options

A. 2.44×10^2 J/°C
B. 2.04×10^3 J/°C
C. 1.84×10^2 J/°C
Correct Answer D. 2.04×10^2 J/°C
Correct Answer
D
Correct Option:
2.04×10^2 J/°C
