Two liquids A and B boil at 145 C and 190 C respectively.Which of them has higher vapour pressure at 80 C.Give reason..-

Pre board question

Plz help.What will be the answer

Boiling Point of liquid A = 145⁰C

Boiling Point of liquid B = 190⁰C

Liquid A has lower boiling point, so it is being more volatile and has high vapor pressure at 80⁰C. Because vapour pressure has an inverse relation with boiling point.
