If a liquid has low vapour pressure, how will its volatility be?
Answer and explanation
Correct answer: Low
Volatility is the tendency of a liquid to produce vapour. At the same temperature, low vapour pressure means that relatively few molecules escape and remain in the vapour phase at equilibrium. Therefore the liquid is less volatile. High volatility would instead be associated with a higher vapour pressure, not an infinite or necessarily constant value.
