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.
