I am trying to word this question as best as I can. Once water has reached its bottom-notch state/position, will the temperature increase? I mean, if water changes to steam once heat is added, why won't the temp. increase (or stay constant)? Another question is why won't the temp. rise if heat is added to ice when 0 degrees Celsius is reached? Thanks again, and I'm sorry if I worded this confusingly.
