evporation 3)
hope it help you......

Answer 2

1.) Sublimation as naphthalene balls changes directly to gaseous state from solid state without comming into liquid state.
3.) Evaporation:-as the factor of evaporation "wind" states that rate of evaporation increases with increase in wind speed because particles present on the surface of liquids easily move with wind.
4.) Condensation:-as in this process gas converts into liquid on cooling.
