Gce Model Questions Vol1 2018 Physics Question 45
Practice objective / multiple choice question 45 from the 2018 Gce Model Questions Vol1 Physics examination.
A 150 g block of an unknown metal at 120 °C is placed into an insulated calorimeter containing 250 g of water at 20 °C. After equilibrium the water temperature is 30 °C and 20 g of the water has evaporated. The latent heat of vaporisation of water is \(L_{v}=2260\;\text{J g}^{-1}\) and the specific heat capacity of water is \(c_{w}=4.18\;\text{J g}^{-1}\text{K}^{-1}\). Determine the specific heat capacity \(c_{m}\) of the metal.
