| 2. How is surface tension measured? | |
Ans. Surface tension can be measured using a tensiometer, which applies a known force to a liquid interface and measures the resulting deformation.
| 3. What factors affect surface tension? | |
Ans. Surface tension is affected by factors such as temperature, type of liquid, and presence of impurities in the liquid.
| 4. How does surface tension affect the behavior of liquids? | |
Ans. Surface tension causes liquids to form droplets or sheets, affects the capillary action in plants, and plays a role in the behavior of bubbles and insects that walk on water.
| 5. Can surface tension be changed? | |
Ans. Surface tension can be changed by adding surfactants or changing the temperature of the liquid, which alters the interactions between the molecules at the surface.
