Question:

A mass 2.4 kg of solid laurasium is initially at temperature 6∘C. It is put into contact with 3.8 kg of liquid tethium which is at temperature 97∘C, and the two chemicals are thermally insulated from the rest of the universe. The specific heat capacity of solid laurasium is 1165Jkg∘C, and the specific heat capacity of liquid laurasium is 3495Jkg∘C. The melting point of laurasium is 22∘C, and the latent heat for its solid liquid transition is 25149Jkg. The specific heat capacity of liquid tethium is 2330Jkg∘C. This material does not undergo a phase transition in this problem. What is the final equilibrium temperature of the laurasium and the tethium? Answer in degrees Celsius. Ans. 54.4
