here,
mass , m = 55 g = 0.055 kg
specific heat of ice , Ci = 2090 J/kg degree C
latent heat of fusion , Lv = 334000 J/kg
specific heat of water , Cw = 4186 J/Kg degree C
the heat energy required , Q = m * ( Ci * ( 0 - (-10)) + Lf + Cw * ( 20 - 0))
Q = 0.055 * ( 2090 * 10 + 334000 + 4186 * ( 20))
Q = 2.41 * 10^4 J
the heat energy required is 2.41 * 10^4 J
