Question

How much energy is required to heat the solid iron from 1535 ∘C to 2000 ∘C?

Answer 1

Answer:

$Q=206.46\frac{J}{g}$

Explanation:

Hello,

In this case, since the energy due to the change of temperature is computed via:

$Q=mCp\Delta T$

Thus, since the specific heat of iron is 0.444 J/(g°C), the heat per unit of mass turns out:

$Q=0.444\frac{J}{g\°C}(2000-1535)\°C\\ \\Q=206.46\frac{J}{g}$

Best regards.
