Which Property of Water Is Demonstrated When We Sweat?
Most of us know that sweating helps control our normal body temperature. However, we often wonder how this is done. Also, we want to know which property of water is demonstrated when we sweat? What are the body processes and substances involved in this physiological occurrence?
The Mechanism of Sweating
First, you must know that sweating is a normal response of the body when its temperature is raised above normal. The normal body temperature is from 36.5 Celsius to 37.3 Celsius. When you have fever and the body temperature rises, this will trigger the body to do something to maintain homeostasis (balance).
The abnormal temperature condition of the body will be fed to the hypothalamus, which will then trigger a series of actions to return the body to its normal temperature. This is called negative feedback mechanism. In this process energy is generated, and sweat is produced. This sweat will help evaporate the heat by releasing it in the gaseous state, and also help cool the skin.
There are sweat glands all over the body except the eyelids. Hence, this helps the body’s temperature go back to normal.
The blood vessels also dilate to release heat from the body. Together with the evaporation of heat, the body would return to its normal temperature. In instances when the fever is caused by a pathological condition, a therapeutic medication may have to be administered.
Which Property of Water is Demonstrated when We Sweat?
The properties of water demonstrated in this occurrence are:
- Boiling Point
Water turns into its gaseous state and evaporates when heated appropriately and the atoms break free from their bonds. But first the hypothalamus in your brain will have to recognize the temperature imbalance. This happens when the heat increases in your body. Once this occurs, the brain automatically responds and triggers the sweat glands to produce sweat.
The sweat then is generated because of the heat energy in your body. It takes energy/heat to produce sweat. That’s why when you exercise; you sweat a lot too, because your physical activity generates energy and heat to trigger the sweat glands. Together with the release of sweat, some toxic substances are released as well, and heat evaporates.
When sweat is generated, it’s liquid in nature and thus has the ability to cool down areas in the body that are warm or hot. Heat then evaporates as the water dries and some become gaseous in form.
The boiling point of water is 100 degrees Celsius. This is the point that it starts to evaporate. Although, during the process of sweating, the temperature of your body doesn’t reach 100 degrees Celsius, heat is still eliminated because of the cooling effect of sweat. Most liquid substances tend to cool down temperatures. Additionally, some of the heat evaporates as the body returns to its normal temperature.
The Other Physical Properties of Water
- It’s colorless
- It’s odorless
- It’s tasteless
- It has no specific gravity
- It’s neutral; neither acidic nor basic
- It’s liquid in form at specified temperatures and pressure
- It’s solid in form at temperatures below 0 degrees Celsius
- It’s gaseous in form at temperatures above 100 degrees Celsius
It’s considered a universal solvent too, and can dissolve almost all solutes and substances, except lipids and similar substances.
I have answered the question: “Which property of water is demonstrated when we sweat?” You have learned that water is a cooling agent, and it can help cool the body when you sweat. You have learned the other physical properties of water as well. Use this as a guideline in using water. Learn how to use water wisely because it’s one of the most important basic commodity that man cannot live without.
