What minimum heat is needed to bring 250 g of water at 20 ∘c to the boiling point and completely boil it away? the specific heat of water is 4190 j/(kg⋅k) and its heat of vaporization is 22.6×105 j/kg.
Answers: 2
=4190 J/kg-k
=heat to raise water temperature from 20 to 100 +Heat to vapourize water completely
