The variation of vapour pressure of different liquids with temperature is shown in fugure
(i) Calculate graphically boiling points 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 liquid D boils?
(iv) Pressure coojer is used for cooking food at hill station. Explain in terms of vapour pressure why is it so?
