1736 - What is the pressure of a gas.

The pressure of a gas is the force that the gas is pushing against the sides of its container. It's like when you blow up a balloon, the air molecules inside are pushing against the rubber, making it expand.

Imagine the gas molecules are bouncing around really fast, and they keep hitting the sides of the container. Each time they hit, they transfer a tiny bit of force to the container. This force adds up and becomes the pressure of the gas.

So, pressure is like the 'push' that the gas is giving to its container. The more molecules bouncing around and hitting the sides, the higher the pressure will be.
