Melting point of water is 32F or 273.15 K
Boiling point of water is 212 F = 373.15 K
First ice is warmed from 10F to 32 F
Heat capacity of ice is 2.09 kJ/kg K
Then ice melts, during this temperature remains same.
For melting, energy is 333 kJ / kg K
Water warms to 305 K.
Heat capacity of water is 4.19 kJ / kg K hi
