1) The energy to heat from the ice 0 ° C to 11C
To melt Energy Plus 2) the ice
To increase 3) Energy Plus Water 0 ° C to 100C
Energy Plus 4) to generate steam
Energy, to 5) for generating steam from 100C to 111C
You need the values of these, something like joules / (1G * 1C).
Once the energy is to 1) 42 * 11 * XJ = joules
