Question
Using the list of physical properties of water below, select the one that is most prominent in the situation described. Adhesion Cohesion Surface tension Heat of vaporization Hydrogen bonding Hydrophilic Hydrophobic Specific heat. A water strider (a type of aquatic insect) can skim on the surface of water without falling through. If a man walks outside on a day that is -40F/-40C and you take his temperature you'll find that it doesn't deviate much from 98F/37C. If you put a drop of oil in water the oil floats on top and does not mix with the water. A dog pants in the heat to cool down. Water being drawn up the vascular tissues of plants from the roots to the leaves (there will be 2 answers for this question).Explanation / Answer
Answer:
1. Surface tension
Explanation:
Water striders use the surface tension of water to their advantage so they can walk on water.
2. Specific heat
Explanation:
Water appears to be colder to us than air. This difference is due to the much higher heat capacity of water than of air. This property of water plays an important role in the maintenance of body temperature.
3. Hydrophobic
Explanation:
Oil is hydrophobic and thus does not mix with water.
4. Heat of vaporization
Explanation:
Panting is the rapid, shallow breathing that speeds evaporation of water from your dog's tongue. So, the process of cooling is performed through latent heat of vaporization.
5. Cohesion, Adhesion
Explanation:
Cohesion is the force of attraction between the water molecules in each narrow xylem tube provides a force that keeps the water column unbroken while it is being pulled up under tension.
Adhesion causes the water molecules to adhere, or stick, to the xylem walls. Along with cohesion, adhesion keeps the water column from breaking as it is pulled upward.
