Ozone is awesome.

CNY is finally over! All the goodies are making me fat.:( Anyways, finally i get to attend my favorite module CM8001! We learnt about ozone today!

Ozone is mostly found in the stratosphere and it does important job – protecting us from ultra violet radiation.  Ultra violet light excites electrons and breaks chemical bonds in our DNA causing skin cancer. (thank god for it i dont want to die)

We also learnt about the Chapman cycle which tells us there is a steady state for ozone which implies that the rate of formation and depletion of ozone is the same.

                   CFC

CFC is the main culprit that causing ozone to deplete. The chlorine in CFC acts as the catalyst in breaking down ozone. It was banned.
