Answer:

We ain't got the necessary data........

Explanation:

We have to supply enuff heat to...

#(i)# heat ice from #-5# #""^@C# to #0# #""^@C#

#(ii)# melt ice at #-0# #""^@C# to give water at #0# #""^@C#

#(iii)# heat water from #0# #""^@C# to #100# #""^@C#

#(iv)# vaporize water at #100# #""^@C# to give steam.

#(v)# heat steam from #100# #""^@C# to #105# #""^@C#

You have supplied none of the data required, the specific heats of ice, water, and steam; the phase transition data. If you can't be bothered to supply the appropriate data, why should we bother to answer your question?
