here,
mass of ice , m = 20 g = 0.02 kg
initial temperature , Ti = - 10 degree C
latent heat of fusion , Lf = 3.34 * 10^5 J/kg
latent heat of vapourisation , Lv = 2.256 * 10^6 J/kg
specific heat of ice , Ci = 2090 J/kg
specifice heat of water , Cw = 4186 J/kg
the heat energy required , Q = m * ( Ci * ( 0 - Ti) + Lf + Cw * ( 100 - 0) + Lv)
Q = 0.02 * ( 2090 * ( 0 - (10)) + 3.34 * 10^5 + 4186 * (100 - 0) + 2.256 * 10^6) J
Q = 5.98 * 10^4 J
