With increase in temperature, the vapor pressure of liquids__________________?
Correct answer: A. Increases
- A. Increases
- B. Increases linearly
- C. Decreases
- D. Remain constant
Explanation
Heating a liquid increases the average molecular energy, allowing more molecules to escape into the vapour phase, so vapour pressure rises. The rise is generally nonlinear with temperature, which makes option A preferable to the more restrictive linear statement.
