Why do surface molecules experience a net force attracting them towards the interior of a fluid?
Why do surface molecules experience a net force attracting them towards the interior of a fluid?
- Due to capillary action forces on the surface
- Due to cohesion forces with neighboring molecules
- Due to adhesion forces with neighboring molecules
- Due to unbalanced forces resulting from lack of neighboring molecules above (correct)
How does surface tension affect small objects or insects placed on water?
How does surface tension affect small objects or insects placed on water?
- It allows them to sink into the water easily
- It creates a thin film on which they can rest (correct)
- It creates an upward force pushing them up
- It repels them away from the water
