Waec Model Questions Vol1 2020 Physics Question 8
Practice essay / theory question 8 from the 2020 Waec Model Questions Vol1 Physics examination. This question covers Heat .
A 150 g block of copper at 80°C is placed into a well‑insulated calorimeter that initially contains 200 g of water at 20°C. The specific heat capacities are: copper c₍Cu₎ = 0.385 J·g⁻¹·K⁻¹, water c₍w₎ = 4.18 J·g⁻¹·K⁻¹. After the system reaches thermal equilibrium the temperature recorded (ignoring the calorimeter’s heat capacity) is 25.0°C. The calorimeter itself has a heat capacity of 12.0 J·K⁻¹ which was not taken into account in the first reading.
