how much heat is needed to change 20g mercury at 20c into mercury vapor at the boiling point

Answer 1

What does dago tell us about the subject?
q1 = heat to move temperature Hg from 20 C to boiling point.
q1= mass Hg x specific heat Hg x (Tfnal-20).
q2 = heat to vaporize Hg.
q2 = mass Hg x heat vaporization.

total heat = q1 + q2.
