Question 46 NECO • 2020 • PHYSICS • objective

A 200 g piece of metal at \(120^{\circ}\text{C}\) is placed into a calorimeter containing 250 g of water at \(25^{\circ}\text{C}\). The calorimeter has a heat capacity of \(0.05\,\text{kJ K}^{-1}\). After the system reaches thermal equilibrium the final temperature is \(30^{\circ}\text{C}\). Assuming no heat loss to the surroundings, determine the specific heat capacity of the metal in \(\text{J kg}^{-1}\text{K}^{-1}\).

Answer Options

Correct Answer A. 3.04\times10^{2}\,\text{J kg}^{-1}\text{K}^{-1}
B. 4.00\times10^{2}\,\text{J kg}^{-1}\text{K}^{-1}
C. 3.50\times10^{2}\,\text{J kg}^{-1}\text{K}^{-1}
D. 2.56\times10^{2}\,\text{J kg}^{-1}\text{K}^{-1}
Correct Answer
A
Correct Option:
3.04\times10^{2}\,\text{J kg}^{-1}\text{K}^{-1}
