An industry has developed a prototype boiler that uses water and steam to heat a denser liquid in an insulated tank. Initially, the water in the boiler is at a temperature of 120ºC and a quantity of 2 kg is injected, while the liquid in the tank is at 25ºC, with a mass of 5 kg and a specific heat of 2000 J/kg·K. Disregarding heat losses to the surroundings, calculate the final equilibrium temperature of the mixture, in ºC, in the system:

56°C

44°C

35°C

38°C

49°C
