Gce Model Questions Vol1 2021 Physics Question 21
Practice objective / multiple choice question 21 from the 2021 Gce Model Questions Vol1 Physics examination.
A copper block of unknown mass \(m\) is placed into a calorimeter containing 0.5 kg of water at 20 °C. The calorimeter has a heat capacity of 50 J °C⁻¹. The initial temperature of the copper block is 150 °C. After the system reaches thermal equilibrium the temperature is 30 °C. Given the specific heat capacity of copper is 0.385 J g⁻¹ °C⁻¹ and that of water is 4.18 J g⁻¹ °C⁻¹, determine the mass of the copper block in kilograms.
