Quiz C2W4

A paper towel absorbs water when you dip it into a glass. Explain how capillary action is involved in this process, and why the water moves upwards against gravity.

When small insects walk on water without sinking, surface tension is responsible. Describe how surface tension allows this to happen and what properties of water are involved.

Water droplets form a round shape on a leaf after it rains. Analyze the role of cohesion in this phenomenon, and explain why the water stays together in this droplet form.

Water sticks to the glass walls of a graduated cylinder, forming a meniscus. Explain the role of adhesion in this scenario and why the water adheres to the surface of the glass.

In a closed system, when vinegar reacts with baking soda to form carbon dioxide gas, the mass before and after the reaction is the same. Analyze how the law of conservation of mass applies to this reaction and why mass is conserved, even though a gas is produced.

A salad consisting of lettuce, tomatoes, and cucumbers is a clear example of a heterogeneous mixture. Analyze what makes this mixture heterogeneous and why the components remain distinct from each other.

When you place a small piece of plastic on water, it floats but adheres slightly to the surface. Discuss how surface tension and adhesion work together in this situation and why the plastic doesn’t immediately sink.

Plants transport water from their roots to their leaves through small tubes. Explain how both cohesion and capillary action contribute to this process, and why these forces are essential for plant survival.

Imagine you're a tiny water droplet in a plant's root, and you've just been invited to a leaf party at the top! Olivia, Henry, and Grace are curious: How does your adhesion to the plant cell walls help you climb all the way up against gravity to join the fun? - *A)* It decreases the energy required for your adventurous journey. - *B)* It boosts the plant's photosynthesis party vibes. - *C)* It helps you stick together, maintaining high surface tension in your travel group. - *D)* It acts like a magical force pulling you upward to the leaf bash.
