Answer:
[tex]Q = 334\,kJ[/tex]
Explanation:
Let assume that 1 kilogram of water in solid state at one atmosphere of pressure. The fussion latent heat of [tex]334\,\frac{kJ}{kg}[/tex], the heat required to change the phase of water is:
[tex]Q = m \cdot L_{f}[/tex]
[tex]Q = (1\,kg)\cdot \left(334\,\frac{kJ}{kg} \right)[/tex]
[tex]Q = 334\,kJ[/tex]
