What is photolysis?

Photolysis is when light breaks apart molecules into smaller pieces, just like sunlight can break apart water into oxygen and hydrogen.

Imagine you have a big block of ice, and it's so cold that it won't melt no matter what. But then the sun comes out and shines on it, poof! The ice starts to turn into water droplets. That’s kind of like photolysis in action.

In nature, this happens with water molecules. When sunlight hits them, especially in plants during photosynthesis, they get split apart into oxygen and hydrogen. It's like giving the water molecule a little push from the sun so it can break apart and do new things.

Think about when you leave a glass of water outside on a sunny day. After a while, you might notice tiny bubbles forming, those are oxygen escaping from the water! That’s photolysis happening right in front of you.

So next time you see bubbles in your drink or feel the sun warming up your skin, remember: the sun is doing more than just making it feel nice, it's breaking things apart too!
