Gce Model Questions Vol1 2023 Physics Question 18
Practice objective / multiple choice question 18 from the 2023 Gce Model Questions Vol1 Physics examination.
A metal rod of unknown specific heat capacity \(c\) (J kg⁻¹ K⁻¹) has a rectangular cross‑section and a length of \(0.30\) m. Its density is \(7800\) kg m⁻³ and its volume is \(3.0\times10^{-5}\) m³. The rod is heated uniformly to \(120^{\circ}\text{C}\) and then placed into an insulated container holding \(200\) g of water initially at \(20^{\circ}\text{C}\). After thermal equilibrium the temperature of the water‑rod system is \(30^{\circ}\text{C}\). During the process the rod loses an additional \(5.0\) kJ of heat to the surroundings. Determine the specific heat capacity \(c\) of the metal, giving your answer to the nearest whole number (J kg⁻¹ K⁻¹).
