SUMMARY
The discussion focuses on calculating the heat energy required to melt a 10 kg block of ice at 0 degrees Celsius into liquid water at the same temperature. The correct formula for this calculation is Q = mL, where Q is the heat energy, m is the mass of the ice, and L is the latent heat of fusion, which is 3.34 x 10^5 J/kg for water. The initial attempt incorrectly used the formula Q = mcΔT, which is not applicable in this scenario since there is no temperature change during the phase transition.
