1. The problem statement, all variables and given/known data How much energy does it take to transform 500 g (0.5kg) of liquid water at 20 oC to steam at 100 oC? Note that the specific heat capacity of liquid water is 4.28x10^3 J/Kg/oC and the latent heat of vaporization for water is 2.3x10^6 J/Kg. 2. Relevant equations Eh=mct ; m1c1t1=-m2c2t2 ; Eh = mLf ; Eh= mLv 3. The attempt at a solution no clue..please help..
