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.

Answer 2

"206.46 J/g" energy required to heat the solid iron.

Energy due to change in temperature:

The movements or the activity of microscopic particles known as atoms, molecules, or ions in solids, solvents, as well as gases.

Thermal energy may go from one item towards the another one.

Given:

Temperature, $T_1 = 1535$°C

                       $T_2 = 2000$°C

Change, $\Delta T = T_2-T_1$

We know the relation,

→ $Q = mC_p \Delta T$

By putting the values,

      $= 0.444(2000-1535)$

      $= 206.46$ J/g

Thus the answer above is right.
