You must go through all of the steps from steam at 130 to ice at -50.
q to move steam at 130 to steam at 100.
q1 = mass x specific heat x delta T.
q to convert steam at 100 to liquid water at 100.
q2 = mass x heat of vaporization.
q to move water at 100 to water at zero.
q3 = mass x specific heat x delta T.
q to convert water at zero to ice at zero.
q4 = mass x heat of fusion.
q to move ice at zero to ice at -50.
q5 = mass x specific heat x delta T.
Then total q =
I notice your specific heats are listed in joules so your answer will come out in Joules and you must convert to kJ since the problem asks for kJ.
