Gce Model Questions Vol1 2018 Physics Question 49
Practice objective / multiple choice question 49 from the 2018 Gce Model Questions Vol1 Physics examination.
200 g of water at 80 °C is mixed with 100 g of ice at -10 °C. The specific heat capacities are 4.18 J g⁻¹ K⁻¹ for water and 2.09 J g⁻¹ K⁻¹ for ice, and the latent heat of fusion of ice is 334 J g⁻¹. (a) Find the final equilibrium temperature of the mixture (in °C). (b) Assuming the heat released by the water can be used to run a Carnot engine operating between the final temperature and 0 °C, calculate the maximum work obtainable (in kJ).
