How Does Relative Humidity Isn't What You Think It Is Work?

Relative humidity is like how full your favorite water bottle is, but not just because it has water in it.

Imagine you have a water bottle that can hold 100 sips of water. If it's got 50 sips, it’s half full. But if it’s really hot outside, the bottle can actually hold more than 100 sips! So even though it only has 50 sips in it, because of the heat, it feels like it’s only a quarter full, that's relative humidity.

How It Changes

When it gets cold, your water bottle can’t hold as much. If you put it in the fridge and now it only holds 80 sips, then 50 sips feel like more than half full, that means the air is drier!

So, relative humidity isn't just about how much moisture is in the air, it's also about how warm or cold the air is. It’s like your water bottle changing size depending on what mood it’s in.

When you're outside and it feels sticky, that means there's a lot of moisture in the air (like your water bottle being almost full). When it feels dry, the air isn’t holding as much, like your water bottle only has a few sips in it!Relative humidity is like how full your favorite water bottle is, but not just because it has water in it.
