Answer:
[tex]s = 382.45 J/kg C[/tex]
Explanation:
Here by energy equivalence we can say that energy given by the metal piece is same as the energy absorbed by the water
so here we have
[tex]m_1s_2\Delta T_1 = m_2s_2 \Delta T_2[/tex]
here we know that
[tex]m_1 = 60 mL = 0.060 kg[/tex]
[tex]s_1 = 4186 J/kg C[/tex]
[tex]\Delta T_1 = 28.5 - 22[/tex]
[tex]m_2 = 59.7 g = 0.0597 kg[/tex]
[tex]\Delta T_2 = 100 - 28.5[/tex]
[tex]0.060(4186)(28.5 - 22) = (0.0597)(s)(100 - 28.5)[/tex]
[tex]1632.54 = 4.27 s[/tex]
[tex]s = 382.45 J/kg C[/tex]
