How much heat,in joules,is required to convert 1.00 kg of ice at 0C into steam at 100C? (Lice = 333 J/g;Lsteam = 2.26 103 J/g. )
Water at room temperature,20C,is pumped into a reactor core where it is converted to steam at 200C.How much heat (in J)is transferred to each kilogram of water in this process? (csteam = 2 010 J/kgC;Lsteam = 2.26 103 J/g;1 cal = 4.186 J. )

B)melting the ice to become water
C)warming the resulting water
D)vaporizing the water to become steam
E)heating the steam
