Bonding Properties of Water

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

The bonding properties of water give it certain characteristics: surface tension, capillary action, universal solvent, high specific heat, and a high heat of vaporization. Indicate three reasons why you believe these properties are important to organisms that live underwater. In your own words, explain one of the following everyday phenomena in regard to the bonding properties of water, and propose one other everyday phenomenon that demonstrates the bonding properties of water:

◦Why do you feel cool when you sweat?

◦Why do paper towels (made of cellulose, another polar molecule) absorb water?

◦How can a water strider walk on water?

Water molecules like to stick to themselves and to other things. Use this idea to develop an answer as to how a water strider can walk on water. I will give you a hint - it has to do with surface tension. Be sure to also investigate adhesion and cohesion, as these two events are very important when considering surface tension.

As far as high specific heat goes and its importance to creatures that live in the water, imagine if a lake found in upstate Maine froze all the way to the bottom. What would happen to ...

Solution Summary

This response provides a framework for the student to answer questions about the bonding properties of water. It suggests possible answers to the proposed questions and gives a few hints as to the direction the student should take in order to develop their understanding of the concepts.

Many of water's unique properties...

1. Many of water's unique properties are the result of its polar covalent bonds, which allow water molecules to form hydrogen bonds with each other. What if water molecules instead had nonpolar covalent bonds? Make a list of hypothesis about the ways in which this change might affect the properites of water. Describe how each change would effect living things. Design an experiment to test one of your hypothesis.

2. Plant roots take up minerals (inorganic ions such as potassium) that are dissolved in the water of the soil. The concentration of such ions is usually much lower in the soil water than in cytoplasm of root cells. Design the plasma membrane of a hypothetical mineral-absorbing cell, with special reference to mineral-permeable channel proteins and mineral-transporting active-transport proteins. Justify you choice of channel proteins and active-transport proteins.
