	$To answer this question, you must using Azaz black$ $m_{1} = 2 kg, △ T_{1} = 100 - 45 = 55^{o} C, c = 4200 J / {kg}^{o} C ({it}^{'} s releasing heat) \to water$ $m_{2} = 0 . 15 kg, △ T_{2} = 45 - 10 = 35^{o} C, c = 4200 J / {kg}^{o} C ({it}^{'} s accept heat) \to water in calorimeter$ $Q_{releasing} = Q_{accept}$ $m_{1} \times c \times △ T_{1} = C_{calorimeter} \times △ T_{2} + m_{2} \times c \times △ T_{2}$ $2 \times 4200 \times 55 = C \times 35 + 0.15 \times 4200 \times 35$ $C = 12570 J /^{o} C$
