Answer: 4276.2 caloriesExplanation:Given

mass of steam is 6 gm at [tex]100^{\circ}C[/tex]

Conversion of steam to ice involves

Calories released during the conversion of steam to water at [tex]100^{\circ}C[/tex]

[tex]E_1=mL_v\quad [L_v=\text{latent heat of vaporisation}]\\E_1=6\times 533=3198\ cal.[/tex]

Calories released during the conversion of water at [tex]100^{\circ}C[/tex] to water at [tex]0^{\circ}C[/tex]

[tex]E_2=mc(\Delta T)\quad [c=\text{specific heat of water,}1\ cal./gm.^{\circ}C]\\E_2=6\times 1\times 100=600\ cal.[/tex]

Calories released during the conversion of water to the ice at [tex]0^{\circ}C[/tex]

[tex]E_3=mL_f\quad [L_f=\text{latent heat of fusion}]\\E_3=6\times 79.7=478.2\ cal.[/tex]

The total energy released is

[tex]E=E_1+E_2+E_3\\E=3198+600+478.2=4276.2\ cal.[/tex]
