A volcano erupts and pours 5.21 × 104 kg of 880°C lava into a 7°C mountain lake of mass 4.38 × 105 kg. The specific heat capacity of the lava is 0.810 J/g°C. What will the temperature of the lake be after the lava flow is finished? Assume that the heat lost by the lake to the surroundings is negligible while the lava is entering the lake.
