I think 3rd ans is 100% correct answer

Answer 2

Answer:

1. bulk phenomenon .Boiling is the bulk phenomenon because in this the particles of the bulk of liquid gain energy and then get converted into gaseous or vapor state.  When a liquid is boiled the heating of substance starts from the bottom of the vessel so that the temperature of the whole liquid reaches its boiling point.

2.surface phenomenon. Evaporation is a surface phenomenon because, during evaporation, the molecules with higher kinetic energy dissipate into the air from the topmost layer of the liquid so it is a surface phenomenon.

3.substance from the solid to the gaseous state without its becoming liquid.Sublimation is the conversion of a substance from the solid to the gaseous state without its becoming liquid. It occurs more frequently among substances that are close to their freezing point. Sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid.
