Original Khojo Papers practice question — not from a past board paper.
33 600 J
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Heat required = mass × specific latent heat = 100 × 336 = 33 600 J. The temperature does not change during melting.

Why is water used as a coolant in car radiators and in industrial cooling?
Calorimetry
Why does the temperature of a substance not change while it is melting, even though heat is being supplied?
Calorimetry
Calculate the heat needed to raise the temperature of 200 g of water from 20 °C to 100 °C. Take the specific heat capacity of water as 4200 J kg−1 K−1.
Calorimetry
Calculate the heat needed to melt 100 g of ice at 0 °C into water at 0 °C. Take the specific latent heat of fusion of ice as 336 J g−1.
