Latent heat of fusion

How much heat is needed to melt 250 g of ice at 0 °C?
ΔHfus = 334 J/g. q = m·ΔHfus.
Given data
m = 250 gΔH<sub>fus</sub> = 334 J/gT = 0 °C
Review the theory: Equilibri tra Fasi
Steps
0 / 1
  1. Calculate q = m·ΔHfus.
Full worked solution
  1. Calculate q = m·ΔHfus.
    250⋅334250 \cdot 334
    q = 250 × 334 = 83,500 J = 83.5 kJ.
Result:q = 83.5 kJ.
