Answer :
The specific heat of the metal is 0.389 J/g·°C.
The specific heat of the metal can be calculated using the formula:
q = mcΔT
where q is the heat absorbed, m is the mass of the metal, c is its specific heat, and ΔT is the change in temperature.
Substituting the given values, we get:
1.43 kJ = (217 g) c (39.1 °C - 24.5 °C)
Solving for c, we get:
c = 0.389 J/g·°C
To predict the identity of the metal, we can compare its specific heat to known values for different metals. Based on the calculated specific heat, the metal is likely aluminum or a similar metal with a specific heat close to 0.9 J/g·°C. However, additional tests would be necessary to confirm its identity, such as measuring its melting point, density, and conductivity.
