If 5.40 kcal of heat is added to 1.00 kg of water at 100⁰C, how much steam at 100⁰C is produced? Show all calculations leading to an answer.

Heat of vaporization of water = 540 cal/g

m=1000 g

energy supplied = 5.4 kcal=5400 cal

T1=T2=100 deg. C

so all energy is used to convert to steam

mass of steam produced = 5400 cal / (540 cal/g)

=5400/540 cal * g/cal

=10 g
