The variation of vapour pressure of different liquids with temperature is shown in Fig. 5.6. 

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? 

This is a long answer type question as classified in NCERT Exemplar

i. The  boiling points of liquid A  is approximately 315 K and of liquid B is approximately 345 K (shown below graphically).

ii. Liquid C in a closed vessel will not boil as the pressure keeps on increasing.
