The variation of vapour pressure of different liquids with temperature is shown in figure below,
(i) Calculate graphically boiling point of liquids A and B.
(ii) If we take liquid C in a closed vessel and heat it continuously, at what temperature will it boil?
(iii) At high altitude, atmospheric pressure is low (say 60 mm Hg). At what temperature will liquid D boil?
(iv) Pressure cooker is used for cooking food at hill station. Explain in terms of vapour
pressure Why is it SO?
