PLS 2 Chapter #5 - Quizizz Capillary Action and Water Quiz

What is capillary action?

• The movement of water within the spaces of a porous material due to adhesion, cohesion, and surface tension

• The absorption of water by plant roots

• The process of water evaporating from the surface of leaves

• The flow of water in rivers and streams

Which forces are responsible for capillary action?

• Adhesion, cohesion, and surface tension

• Gravity and friction

• Pressure and temperature

• Magnetism and electricity

Why is capillary action important for plants?

• It helps plants grow taller

• It helps plants produce oxygen

• It helps plants absorb sunlight

• It helps bring water up into the roots and to the branches and leaves

What happens when you dip a paper towel into a glass of water?

• The towel dissolves in the water

• The water evaporates immediately

• The water changes color

• The water climbs up the towel due to capillary action

What is the role of surface tension in capillary action?

• It increases the temperature of the liquid

• It acts to hold the surface of the liquid intact

• It repels water molecules from the surface

• It decreases the viscosity of the liquid

What is a meniscus?

• A type of water molecule

• A type of plant root

• A curve in the surface of a liquid when it touches another material

• A type of soil particle

How does capillary action help in the drainage of tear fluid from the eye?

• By absorbing the tears into the skin

• By pushing the tears out of the eye

• By evaporating the tears

• Through the lacrimal ducts in the inner corner of the eyelid

What is the function of xylem in plants?

• To produce flowers

• To move water and nutrients from the roots to the leaves

• To absorb sunlight

• To store food

What experiment can demonstrate capillary action in plants?

• Weighing the roots of a plant

• Measuring the height of a plant

• Placing a celery stalk in colored water and observing the color move to the leaves

• Counting the number of leaves on a plant

What is the significance of capillary action in a fountain pen?

• It increases the writing speed

• It changes the color of the ink

• It keeps the ink flowing onto the paper

• It prevents the ink from drying
