Problem

150\,\text{g}

sample of an unknown metal cools from

125^{\circ}\text{C}

74^{\circ}\text{C}

while releasing

2.85\,\text{kJ}

of energy. What is the specific heat capacity of the metal? a)

0.56\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

0.19\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

0.37\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}

3.73\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}
