The importance of water Water is one of the weirdest compounds known to humans. The difference between the boiling point and freezing point of water is one of the largest ranges of any compound. It is this span of temperature that mirrors the range of where life can exist, from bacteria to humans. Water also has a very high specific heat, which means that it can absorb or lose much heat before its temperature changes. This is important in maintaining body heat in mammals. It also takes a lot of energy before vaporization can occur. For this reason, water evaporates slowly from ponds and lakes, where many life forms are dependent n a stable, warm environment. Water is less dense in its solid state than in its liquid state, so that ice floats instead of sinking. This property permits life to develop in polar and sub Polar Regions where ice floats and allows life to continue living below the surface. If ice were heavier than water, it would sink, and more ice would form on top of it. As a result, all life in the waters would be trapped in the ice in the many areas of the world where it gets cold enough to freeze water. Water is a remarkable solvent, where most elements and compounds can dissolve in its powerful molecular structure.
Gases such as oxygen and carbon dioxide can also dissolve, making it readily available for photosynthetic and no photosynthetic organisms to use. Water also exhibits viscosity. One can observe the effects of viscosity alongside a stream or river with uniform banks. The water along the banks is nearly still, while the current in the center may be swift. This resistance between the layers is called viscosity. This property allows smaller fish to live near the shore, while larger fish are able to swim efficiently in strong currents.
Viscosity is also responsible for the formation of eddies, creating turbulence that leads to good mixing of air in the water and more uniform distribution of microscopic organisms. Ways to prevent water wastage With a few small, simple changes, you can help reduce your water use, leaving more water in the rivers, lakes and other freshwater sources. These changes will also result in a lower water bill so should benefit your home finances as well: 1. Consider cutting a little water usage from your morning routine. Keeping a timer in your bathroom will remind you to wrap up and get out of the shower faster. 2.
If a home renovation is in the cards, splurge on low-flow and water-efficient appliances they’ll save you money in the long-run. A front-loading washing machine, for example, uses 40-60% less water than top-loading machines. 3. A new toilet can save you water too, but if you can’t install a low-flow toilet, reduce the amount of water used by placing a jar or other closed container full of water into your toilet tank. 4. Install low-flow shower heads and sink spigots, which can both be purchased at your local hardware store, or contact your water utility company to find out if they distribute them for free. 5.
When running the dishwasher, make sure it’s full to get the maximum use per drop. There’s no need to pre-rinse, since most of today’s models can handle any kind of grime. 6. Check for–and hastily repair– leaky pipes and faucets. The tiniest leak has far greater impact than you’d think. 7. Don’t use your sinks and drains as trash cans, and dispose of oil and other toxic materials properly. Just one gallon of oil reaching the sewer can contaminate one million gallons of fresh water. 8. Reduce water use in your own yard: Try collecting rainwater by placing containers at the end of each gutter. It’s perfect for atering your garden; water your lawn or garden in the morning or the evening when the water will evaporate less rapidly, and limit pesticide use, as they’ll eventually be carried into our freshwater supply by runoff. 9. Take the easy way out and hit the car wash. A car wash typically uses about 32 gallons of water per vehicle, but the EPA estimates that washing it yourself can use up to 500 gallons of water. 10. Take advantage of recreation opportunities on local lakes and rivers, and learn about the wildlife they support. It will help you understand what we could lose if we don’t manage our water wisely.
