Question
Substance A has stronger intermolecular forces tha substance B. Both are liquids at room temperature. Which of the statements are true for these liquids under the same conditions of temperature and pressure?
1. The surface tension of A will be greater than the surface tension of B.
2. The vapor pressure of A will be greater than the vapor pressure of B.
3. The viscosity of A will be greater than the viscosity of B.
A. 1 only
B. 2 only
C. 3 only
D. 1 and 3
E. 1, 2, and 3
Please explain the answer in detail, please! :)
Explanation / Answer
he tendency of a liquid to resist increasing its surface area is called surface tension.
Liquids with stronger intermolecular forces, such as polar liquids, exhibit more surface tension.
Capillary action is the spontaneous rising of liquid in a narrow tube, which occurs due to intermolecular forces. (See image to the left.)
Surface tension causes the liquid to rise, ending with the liquid's surface as a meniscus.
Viscosity measures a liquid
