Why energy is required to break bond? Hello friends in today's blog I will tell you about " Why energy is required to break bond? " If you don't read blog about why energy is released  when bonds are formed? See it  here Now,lets talk about our topic. In the    previous blog.  I have tell you why bond making release energy. Bond is like a force that hold electron together to move electron we have to give them energy. Cause to move a body we have to expend some energy on it. If you have any doubts let me know in comment section.

Why energy is liberated in bonding? So here is the reason: When 2 electrons make bond they stop at a position. Before making a bond they are revolving but when they stop the energy they have is liberated. So it is reason why energy is given out when electrons make bond. *this is true somewhat, It is my own idea. This can be useful to teach students. Why energy is liberated? If you have any query let me know in comments.

I think all of you have question why we use x as variable not "-x"? So after researching all night I found the answer, so here it is. If we take +ve sign with variable we find real sign of the answer l. For e.g.  +(+ve)=+ve +(-ve)=-ve Here if sign of x is negative -ve then answers sign or operation us changed. If we use - sign then we gave to reverse the sign of answer also. For e.g. 2+__ =3 1. If value be x then   2+x=3,   x=1 2. If value is -x  2-x=3  x=-1. HOPE ALL OF YOU HAVE UNDERSTOOD IF HAVE ANY DOUBT TELL IN COMMENT SECTION.
