B. Surface tensionExplanation
This image demonstrates how surface tension is beneficial to living organisms. Surface tension is the cohesive force between molecules at the surface of a liquid, creating a "skin" that allows certain organisms to walk on water or create structures such as water striders. This property also helps organisms like insects, spiders, and plants to trap and collect water for survival. Surface tension also plays a role in the movement of water in plants through capillary action, allowing nutrients and water to be transported efficiently.Rate this question:

Adhesion leads to ________________, which is the characteristic of water in which explains the molecular absorption of water into a root or stem of a plant.
- A.
Adhesion
- B.
Surface tension
- C.
Polarity
- D.
Capillary action
- E.
Specific heat
Correct Answer
D. Capillary actionExplanation
Capillary action is the phenomenon where water is able to move against gravity through narrow spaces, such as the tiny tubes in a plant's root or stem. This is possible due to the adhesive forces between water molecules and the walls of the capillaries. The water molecules are attracted to the capillary walls, causing them to rise and be absorbed into the plant. Therefore, capillary action is the characteristic of water that explains its molecular absorption into a plant's root or stem.Rate this question:

Humans have physiologically adapted to sweat if the body temperature rises past ideal levels. The ability to do so helps cool the body down. The polarity of water allows water to have a high _________________________, which allows us to maintain homeostasis and survive as we are today.
- A.
Polarity
- B.
Specific heat
- C.
Cohesive rate
- D.
Adhesive rate
- E.
Surface tension level
Correct Answer
B. Specific heatExplanation
Water has a high specific heat, which means that it can absorb and retain a large amount of heat energy without significantly changing in temperature. This property allows water to effectively regulate body temperature through sweating. When we sweat, water evaporates from our skin, taking away heat from our body and cooling us down. The high specific heat of water helps in maintaining homeostasis, the stable internal temperature necessary for our survival.Rate this question:

During the water and string excitement, the factor keeping the water bonded to the string was the concept of _____________________.
- A.
Cohesion
- B.
Surface tension
- C.
Capillary action
- D.
Density
- E.
Adhesion
Correct Answer
E. AdhesionExplanation
The correct answer is adhesion. Adhesion refers to the attraction between molecules of different substances. In the case of the water and string excitement, the water molecules are attracted to the string molecules, causing them to bond together. This is why the water stays bonded to the string and does not fall off.Rate this question:

The first falling leaf of the season has tumbled from the air and landed on the top of the pond. It does not sink but yet float on top of the surface. What is happening on a molecular level that is preventing the leaf from sinking?
- A.
The covalent bonds between the oxygen and hydrogen atoms are not breaking apart due to the lack of weight placed upon them.
- B.
Both oxygen and hydrogen are positively charged and therefore much stronger.
- C.
There is not enough weight to break the hydrogen bonds between water molecules at the surface of the water.
- D.
The surface area of the leaf is quite large and is breaking the hydrogen bonds of the water molecules on the surface.
- E.
Both C and D.
Correct Answer
C. There is not enough weight to break the hydrogen bonds between water molecules at the surface of the water.Explanation
The first falling leaf of the season is able to float on top of the surface of the pond because there is not enough weight to break the hydrogen bonds between water molecules at the surface. Hydrogen bonds are relatively weak compared to covalent bonds, but they are still strong enough to hold the leaf up. The surface tension created by these hydrogen bonds allows the leaf to remain on top of the water rather than sinking.Rate this question:

What type of bonds interconnects the molecules shown in this image?
- A.
Ionic
- B.
Covalent
- C.
Hydrogen
- D.
Polar
- E.
Both C and D
Correct Answer
C. HydrogenExplanation
The molecules shown in the image are interconnected by hydrogen bonds. Hydrogen bonds occur when a hydrogen atom is bonded to an electronegative atom (such as oxygen or nitrogen) and is attracted to another electronegative atom in a different molecule. This type of bond is weaker than covalent or ionic bonds but is still important in many biological processes, such as DNA replication and protein folding.Rate this question:

Water molecules bond in a crystalline form as the temperature of water drops. This creates more space between water molecules. What characteristic of water does this change describe?
- A.
Specific heat
- B.
Density
- C.
Adhesion
- D.
Surface tension
- E.
Polarity
Correct Answer
B. DensityExplanation
As the temperature of water drops, water molecules bond in a crystalline form, which causes them to arrange themselves in a more organized structure. This arrangement increases the space between water molecules, leading to a decrease in the overall density of water. Therefore, the change described in the question is related to the characteristic of density.Rate this question:

Capillary action involves the following THREE properties of water: adhesion, ________________, and surface tension.
- A.
Density
- B.
Polarity
- C.
Non-polarity
- D.
Cohesion
- E.
Capillary action
Correct Answer
D. CohesionExplanation
Cohesion is the correct answer because it is one of the three properties of water that is involved in capillary action. Cohesion refers to the attraction between molecules of the same substance, in this case, water molecules. This cohesive force allows water molecules to stick together and form a continuous column in a narrow tube, such as a capillary. This cohesive force, along with adhesion (attraction between water molecules and the walls of the capillary) and surface tension, enables water to move against gravity in capillary action.Rate this question:

What is meant by the fact that water is a "polar" molecule?
- A.
Water has a slightly negative charge overall.
- B.
Water has no evident charge unless in sold form.
- C.
Water has a very evident charge, but only in a gaseous form.
- D.
Water has a slightly positive charge, but only as a liquid.
- E.
None of the above.
Correct Answer
E. None of the above.Explanation
The correct answer is "None of the above" because water is a polar molecule due to its bent shape and the unequal distribution of electrons between the oxygen and hydrogen atoms. This results in a slight negative charge on the oxygen atom and slight positive charges on the hydrogen atoms.Rate this question:

Which best describes how hydrogen bonds are created?
- A.
The negative charge of oxygen binds with the positive charge of hydrogen on an adjacent molecule.
- B.
The positive charge of oxygen binds with the negative charge of hydrogen on an adjacent molecule.
- C.
The negative charge of oxygen binds with the positive charge of hydrogen within the SAME molecule.
- D.
The negative charge of oxygen binds with the positive charge of hydrogen within the SAME molecule.
Correct Answer
A. The negative charge of oxygen binds with the positive charge of hydrogen on an adjacent molecule.Explanation
Hydrogen bonds are created when the negative charge of oxygen in one molecule forms an electrostatic attraction with the positive charge of hydrogen in an adjacent molecule. This attraction is relatively weak compared to covalent or ionic bonds, but it is important in many biological and chemical processes.Rate this question:

- A.
Cohesion
- B.
Adhesion
- C.
Specific heat
- D.
Polarity
- E.
Density
Correct Answer
E. DensityExplanation
The polar bear is relying on the property of density in relation to the ice cap. Density refers to the mass of a substance divided by its volume, and it determines whether an object will float or sink in a fluid. In this case, the polar bear is able to walk on the ice because the density of ice is lower than that of water. This allows the ice to support the weight of the polar bear without sinking.Rate this question:
