    In 2007 war between 2 of the strongest political parties has distroyed

    this forum, even moderators were killed, kept in jail, and some have

    been kicked out.

    but now after 20 years , i started thinking we could have done some

    thing better. u might ask what is that thing

    i have sailed this website trying to find a place where i can find

    science , but unfortunately i didnt find

    so i decided to create one on the english forum

    i hope u help me to keep it alive

    first topic will be about

    fans increases the temperature but u feel cooler how

    my regards

    How do fans make you feel cooler?


    You are right -- fans actually add heat to a room. One way to think

    about it is like this: If you have a perfectly insulated room and you

    put an electric fan in it, then the room will get warmer. All the

    electricity that is driving the fan turns directly into heat.

    So a fan does not cool the room at all. What a fan does is create a

    wind chill effect.


    When weatherpeople talk about wind chill on a cold winter day, what

    they are referring to is how the wind increases convective heat loss

    By blowing air around, the fan makes it easier for the air to

    evaporate sweat from your skin, which is how you eliminate body

    heat. The more evaporation, the cooler you fee

    How about just posting a link to how stuff works

    http://science.howstuffworks.com/question22.htm

    I hope you had more in mind for a science section on this English forum. I actually like the idea and love science.

    I look forward to seeing more interesting posts

    If you do decide to copy and paste like some expert pasters at this forum, please add a link to give credit to the real author


    I am more interested in why you decided this information is important
    let me guess global warming
