Explanation:
Q1:- Yes it is true that sublimation does not require heating . Sublimation is a process of conversion of solid into vapor state and vapour into solid state without coming in liquid state. ... And this happens not because of heat it is a natural phenomenon as it gains the heat from the surface .
Q2. :- Yes boiling is considered as bulk phenomenon because total molecules (including interior molecules along with surface molecules) are involved during boiling of any liquid. ... Whereas evaporation is a surface phenomenon. Only the particles on the surface gain enough energy to get converted into vapour state.
