Question

I need help with solving this problem...Calculate the heat in joules needed to melt 16.0 of ice at 0 .

Answer 1

The ice is already at the melting/freezing point. Therefore, the only heat we need to add is that of the heat of fusion. \[Q = m \cdot H_{fus}\]

Answer 2

you need to calculate the head Q=mc(Tf-Ti) {but Tf=Ti so this Q is zero}
and the latent heat of fusion using Q=m*Hfice
add those two and get the answer
