Tensión superficial

The video explains how the attraction between molecules in a liquid causes the surface to behave like an elastic skin, which can support small objects. This phenomenon, known as surface tension, allows small insects to walk on water.

What causes the surface of a liquid to behave like an elastic skin?

• The weight of the liquid

• The temperature of the liquid

• The attraction between its molecules

• The color of the liquid

What role does molecular attraction play in surface tension?

• It decreases the surface area

• It increases the temperature

• It creates an elastic-like surface

• It changes the liquid's color

How does surface tension affect small objects placed on a liquid surface?

• It makes them sink immediately

• It allows them to float due to the elastic nature of the surface

• It changes their color

• It heats them up

Which of the following is a result of surface tension?

• Liquids evaporating faster

• Liquids changing color

• Liquids freezing at higher temperatures

• Small insects being able to walk on water

Why can some insects walk on water?

• Due to the water's temperature

• Because they have special feet

• Due to the surface tension of the water

• Because they are very light
