Question

What are the factors affecting vapour pressure?

✓

Answer

Factors affecting vapour pressure:

Nature of liquid: Liquids having relatively weak intermolecular forces possess high vapour pressure. Such liquids are called volatile liquids.
e. g. Petrol evaporates quickly than motor oil. Hence, petrol has higher vapour pressure than motor oil.
Temperature: When the liquid is gradually heated, its temperature rises and its vapour pressure increases.
