0.5kg of water at 10ºC is completely converted to ice at 0ºC by extracting (88000) of heat from it. If the specific heat capacity of water is 4200jkg\(^{1}\) Cº. Calculate the specific latent heat of fusion of ice.

The answer is not in the option
Q = mL + mct
where,
Q = 88000
m = 0.5
c = 4200
t = 10
88000 = 0.5L + (0.5×4200×10)
88000 = 0.5L + 21000
88000 - 21000 = 0.5L
67000 = 0.5L
L = 67000/0.5
L = 134000
