to calculate the heat needed to melt a block of ice at its melting point what do you need to know?
A.The mass and amount of work done
B.The mass, temperature change, and specific heat capacity.
C.The mass and the latent heat of vaporization.
D.The mass and the latent heat of fusion.

As per the definition of latent heat of fusion we know that it is defined as the heat required to melt a given substance completely when the given substance is at its melting point point.

So here we can say that latent heat of fusion is given as

[tex]L_f = \frac{Q}{m}[/tex]

now if the heat is required to melt the given substance when it is at its melting point then it is given as

[tex]Q = mL_f[/tex]

so here correct answer is given as

D.The mass and the latent heat of fusion.
