q1 = heat released going from steam at 125 to steam at 100.
q1 = mass steam x specific heat steam x delta T.
q2 = heat released to condense steam at 100 to liquid water at 100.
q2 = mass steam x heat vaporization.
q3 = heat released going from water at 100 to water at zero.
q3 = mass H2O x specific heat water x delta T.
q4 = heat released to freeze water at zero to ice at zero.
q4 = mass water x heat of fusion.
q5 = heat released for ice going from zero to -125.
q5 = mass ice x specific heat ice x delta T.
Total q = q1 + q2 + q3 + q4 + q5.
Post your work if you get stuck.
Calculater the amount of heat in kilojoules released when 50 grams of steam at 125 C are converted to 50 grams of ice at -125 C?
