A 150 g piece of copper at \(120^{\circ}\text{C}\) is placed into 200 g of water at \(25^{\circ}\text{C}\) in an insulated calorimeter. After equilibrium the temperature is \(30^{\circ}\text{C}\).\n(a) Assuming no heat loss to the surroundings, calculate the specific heat capacity of copper.\n(b) If the calorimeter itself absorbs \(5.0\ \text{kJ}\) of heat during the process, determine the corrected specific heat capacity of copper.

Answer Options

A. 0.35 J·g⁻¹·°C⁻¹, 0.72 J·g⁻¹·°C⁻¹
