[tex]$\boxed{115.898{\text{ kJ}}}$[/tex] of heat is required to completely melt 347 g ice.
Further explanation:
Latent heat
The heat released or absorbed during the process of conversion physical state of a substance without altering the temperature is known as the latent heat.
The latent heat of fusion of ice is 334 J/g.
When the physical state changes from the solid phase to liquid phase then the amount of heat absorbed in this process to completely convert the solid into liquid without altering the temperature is known as the latent heat fusion.
The formula to calculate heat absorbed from latent heat of fusion is,
[tex]${\text{q}}={\text{m}}{{\text{H}}_{\text{f}}}$[/tex] …… (1)
Here,
q is heat absorbed.
m is mass of substance.
[tex]${{\text{H}}_{\text{f}}}$[/tex] is latent heat of fusion.
The mass of given ice is 347 g.
Substitute 347 g for m and 334 J/g for [tex]${{\text{H}}_{\text{f}}}$[/tex] in equation (1).
[tex]$\align{{\text{q}}&={\text{m}}{{\text{H}}_{\text{f}}}\cr&=\left( {347{\text{ g}}} \right)\left({334{\text{ J/g}}}\right)\cr&=115898{\text{ J}}\cr}$[/tex]
