Points in favour:
1.Diffusion helps reduce the pollution of toxic gases.
Points against:
1. old stains of ink, tea/coffee, cooked food are hard to remove through diffusion, or just hard to remove ...
HELP PLS....V.V.IMPORTANT
It isn't obvious to me what question you are asking.
When a toxic gas such as nitrogen dioxide, sulfur dioxide, sulfur trioxide, chlorine or ammonia is accidentally released into the air it can cause extreme damage to all living organisms close to the point of leakage, however, when diffusion occurs, the gas, spreading over a larger area, would be of a lower concentration and therefore cause lesser damage to each individual. However this can also be seen as disadvantage of diffusion as without diffusion, the gas might not have leaked in the first place and it also spreads through a larger area due to diffusion, thereby affecting more people.
Old stains of ink, tea/coffee and cooked food are hard to remove due to diffusion as they stain a larger area and also diffuse through the layers of the cloth, making the stain more stubborn.
P.S. The points against one is just a hunch and I'm not really sure about that. I suggest you take a better source for that one, but I'm confident about my first answer. And your question isn't very clear, try rephrasing it. Good luck! :)
Old stains of ink, tea/coffee and cooked food are hard to remove as over time, the liquid diffuses into the cloth as well. Since the stain is not just on the surface but has also been absorbed by the cloth, it is harder to remove it.
To address your concern about the difficulty in removing old stains through diffusion, it's important to note that diffusion is a process by which particles spread out from an area of high concentration to an area of low concentration. While diffusion can help reduce pollution of toxic gases, it may not be the most effective method for stain removal.
When dealing with old stains like ink, tea/coffee, or cooked food, there are alternative methods you can try to remove them. Here's a step-by-step process you can follow:
1. Identify the type of stain: Different stains require different treatments. Ink stains, for example, may require a different approach compared to coffee or cooked food stains. This will help you choose an appropriate stain removal method.
2. Pre-treat the stain: Before attempting any stain removal method, it's often helpful to pre-treat the stain by blotting it gently with a clean cloth or paper towel. This can help remove any excess substance on the surface.
3. Choose a stain remover: There are various stain removers available on the market, such as commercial stain removers, dishwashing liquid, or household products like baking soda, vinegar, or hydrogen peroxide. Select the appropriate stain remover based on the type of stain and the fabric/material involved.
4. Apply the stain remover: After selecting a stain remover, follow the instructions provided on the product label or use a solution that you've prepared yourself. Apply the stain remover directly to the stained area and let it sit for the recommended amount of time.
5. Gently agitate the stain: Once the stain remover has had time to work, you can gently agitate the stain by rubbing the fabric together or using a soft brush or sponge. Be careful not to damage or fray the fabric.
6. Rinse the fabric: After agitating the stain, rinse the fabric thoroughly with cold water to remove the stain remover and any remaining residue. Hot water can sometimes set the stain, so it's best to use cold water.
7. Launder as usual: Once the stain has been treated, launder the fabric following the care instructions on the garment. This typically involves washing in a washing machine with an appropriate detergent and water temperature.
Remember, the key to successful stain removal is to act promptly and to always test any stain remover on a small, inconspicuous area of the fabric before applying it to the stain directly. If the stain persists, consider seeking professional help or contacting a dry cleaner who specializes in stain removal.
While diffusion is beneficial for reducing pollution, for stubborn stains, it's necessary to implement specific stain removal techniques.
