To ascertain the temperature of flue gases, 1.8 kg of copper of specific heat 0.395 kJ/kg-°K was suspended in the flue until it attained the temperature of the gases, and then dropped into 2.27 kg of water at 20°C. If the resultant temperature of the copper and water was 37.2°C , find the temperature of the flue gases.
