let me try ...
E=mc(change of temperature )+ml
=( 25*5/1000)(4200)(100-initial temperature )+(25*5/1000)(latent heat of steam)
your information is not sufficient to solve this question .
the question should give the initial temperature and the latent heat of steam .
i also agree with the above guy
you seems like a F3 student from HK
