How much energy is required to melt a 500. gram block of iron? The heat of vaporization is 6090 J/g and the heat of fusion is 247 J/g. 3.05x10 6 J
2.47x10 2 J
1.23x10 5 J
6.09x10 3 J

Heat required = 1.23×10⁵J

Explanation:

Given:

Mass (m) = 500 gram

Specific heat = 6,090 J/g

heat of fusion = 247 J/g.

Find:

Heat required

Computation:

Heat required = 247 J/g× 500 g

Heat required = 1.23×10⁵J

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
