درباره وبلاگ



مدیر وبلاگ : گروه شیمی منطقه 4

آتشفشان کاوا ایجن ( Kawah Ijen ) که در جاوای شرقی اندونزی قرار دارد ، در طول روز گدازه های قرمز از خود بیرون می فرستد و در شب به دلیل فعل و انفعالات شیمیایی خاص ، گدازه های آن به رنگ آبی درمی آید.

 
 علت رنگ آبی گدازه‌ها ، سوختن گوگرد موجود در این گدازه ها است . شعله‌ی سوختن گوگرد آبی رنگ است . هر چند در طول روز نیز گوگرد موجود در این گدازه‌ها می‌سوزد اما نور خورشید ، بر نور آبی  آن غلبه می کند .

در تصویر زیر ، گوگرد موجود در این گدازه را به رنگ زرد مشاهده می‌فرمایید .

I know this if off topic but I'm looking into starting my own blog and was wondering what all is required to get set up? I'm assuming having a blog like yours would cost a pretty penny? I'm not very web smart so I'm not 100% sure. Any suggestions or advice would be greatly appreciated. Many thanks

The other day, while I was at work, my sister stole
my iPad and tested to see if it can survive a thirty foot drop, just so she can be
a youtube sensation. My iPad is now broken and she has 83 views.
I know this is entirely off topic but I had to share it with someone!

When I initially commented I clicked the "Notify me when new comments are added" checkbox
and now each time a comment is added I get three e-mails with the same comment.

Is there any way you can remove me from that service?
Thank you!

I visited multiple blogs however the audio quality for audio songs existing at this website is in fact
excellent.
