Final answer:
To determine the specific heat capacity of the metal, we can use the equation Q = mcΔT, where Q represents the heat energy transferred, m represents the mass of the substance, c represents the specific heat capacity, and ΔT represents the change in temperature. By setting the heat energy for the metal and water equal, we can solve for the specific heat capacity of the metal. In this case, the specific heat capacity of the metal is approximately 0.879 J/g°C.
Step-by-step explanation:
To answer this question, we can use the equation Q = mcΔT, where Q represents the heat energy transferred, m represents the mass of the substance, c represents the specific heat capacity, and ΔT represents the change in temperature.
For the metal, we have m = 34.5 g, ΔT = (39°C - 75°C) = -36°C, and c is what we need to find.
For the water, we have m = 64.0 g, ΔT = (39°C - 25°C) = 14°C, and c = 4.18 J/g°C.
Setting the heat energy for the metal and water equal, we can solve for c:
mc(ΔT) for metal = mc(ΔT) for water
(34.5 g)(c)(-36°C) = (64.0 g)(4.18 J/g°C)(14°C)
Solving for c, we find c ≈ 0.879 J/g°C. Therefore, the specific heat capacity of the metal is approximately 0.879 J/g°C.
