What is the quantity of thermal energy needed to 0,10kg convert ice at -10 degree Celsius into steam at 100 degree Celsius

Answer 1

heat of warmingice:
heat=mass*cice*(10C) where cice is specific heat content of ice
Heat of melting ice:
heat=mass*Hf where Hf is heat of fusion of ice
Heat of warming water:
mass*Cwater*100

add the heats to get total heat.

Answer 2

and add heat of vaporization to steam
