    0Thank You

    Tarannum Jahan 4 years, 11 months ago

    Exothermic reactions release heat or energy.When  you or we breath out,breath is warmer.This is happened for respiration reaction of our body. Carbolydrates present in food are broken down to form glucose.This glucose combines with oxygen in the cells of our body and provides energy.This reaction is known as respiration.hence,respiration is considered as an exothermic reaction.

    Atmospheric refraction is the phenomenon of bending of light rays in the atmosphere. It is called as Atmospheric refraction because there are many layers for the atmosphere. When any sought of light enters the atmosphere it should experience the refraction by different layers. This process happens in the atmosphere. When this light reaches our eyes we doesn't see the apparent position of the way of light. Thus we can name this phenomena as Atmospheric Refraction. This is used by stars for twinkling, formation of rainbow etc....
