What is Pascals (Pa)?

Pascals (Pa) are a way to measure pressure, which is like how hard something is pushing on another thing.

Imagine you're sitting on a soft chair, it feels gentle because the pressure isn’t too strong. But if you sat on a tiny, pointy stool, it would feel much harder, that’s more pressure!

One Pascal is a very small amount of pressure. It's like pressing gently with your finger on a balloon, just enough to make it squish a little.

Think about blowing up a balloon. The air inside pushes against the rubber, that’s pressure. If you blow harder, the pressure increases, and the balloon gets bigger.

If you have a bicycle pump, when you push down on it, you're making the air inside the pump squish together, increasing the pressure, so it can go into your tire!

So, Pascals are just another way of counting how hard something is pushing, like your finger on a balloon or air inside a tire. The bigger the number of Pascals, the harder the push!
