Boiling of liquid decreaseds with lowering of external pressure-why?

Why does the boiling point of a liquid incrase with the increase in the external pressure?

Which of the following is correct regarding boiling and evaporation ? (i) Both boiling and evaporation take place in closed as well as open containers. Evaporation takes place only from the surface of liquid, while boiling involves the formation of bubbles below the surface. (iii) Evaporation takes place at all temperatures , while boiling takes place only at one particular temperature. (iv) Boiling point decreases if the external pressure is low but evaporation increases if the external pressure is low
