Between two liquids, the one with lower boiling point generally has what kind of vapour pressure at the same temperature?
Answer and explanation
Correct answer: Higher
Boiling begins when vapour pressure equals external pressure. A liquid with a lower boiling point reaches that required pressure at a lower temperature, which indicates a greater tendency to vaporize. Therefore, when compared at the same suitable temperature, it generally has the higher vapour pressure. This relation assumes comparable pressure conditions and no unusual phase behaviour.
