What Causes the ‘Fog’ in a Bathroom After a Hot Shower?

When you take a hot shower, your warm body and the hot water make lots of tiny water particles in the air. These particles move to cooler places like the mirror or the glass window. When they cool down, they change from gas to liquid, and that’s what makes the ‘fog’ appear! It's like when you put a cold drink on a warm table and see water droplets form around it.
