Question 43 NECO • 2023 • PHYSICS • objective

A 0.5 kg copper block (specific heat \(c_{\\text{Cu}} = 0.385\,\text{kJ kg}^{-1}\text{K}^{-1}\)) initially at \(20^{\\circ}\text{C}\) is placed in a calorimeter containing 200 g of water at \(80^{\\circ}\text{C}\). No heat is lost to the surroundings. After equilibrium the final temperature is \(30^{\\circ}\text{C}\). Assuming the calorimeter was initially at the same temperature as the copper block, calculate the heat capacity of the calorimeter (in kJ K^{-1}), to two significant figures.

A. 5.6 kJ K^{-1}

B. 2.5 kJ K^{-1}

Correct Answer C. 4.0 kJ K^{-1}

D. 3.2 kJ K^{-1}

Correct Answer

Correct Option:

4.0 kJ K^{-1}
