Calculate the minimum work required to manufacture 3.0kg of ice cubes from water initially at 0C. Assume that the surroundings are at 30C. The latent heat of fusion of water at 0C is 338.7kJ/kg.(adsbygoogle = window.adsbygoogle || []).push({});

My working:

[tex]e=1-\frac{273}{303}[/tex]

then

[tex]e=\frac{work}{input}[/tex]

[tex]input=(3.0)(338.7E3)[/tex]

[tex]work=100.6kJ[/tex]

But I saw the other answer from someone that it is 117.1kJ. Which one is the correct answer? Is my answer correct? If not, please rectify for me. Thanks.
