Question

How is the pressure of a gas determined?

Answer 1

$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

The rapid motion and collisions of molecules with the walls of the container causes pressure (force on a unit area). Pressure is proportional to the number of molecular collisions and the force of the collisions in a particular area. The more collisions of gas molecules with the walls, the higher the pressure.

Answer 2

Answer:

The pressure that a gas produces on the walls of its container is known as its pressure. The gas pressure can be measured in the SI units of pascal and kilopascal, as well as a variety of other units such as torr, atmosphere, and bar.

Explanation:

Pressure is created by the rapid mobility and collisions of molecules with the container's walls. The amount of molecular collisions and the force of those collisions in a given area determine the pressure. The higher the pressure, the more gas molecules collide with the walls.

The pressure that a gas produces on the walls of its container is known as its pressure. When you blow air into a balloon, the envelope opens, and the pressure of the air molecules inside the balloon is higher than on the outside. Pressure is a characteristic that determines the direction in which mass flows.

Gas pressure is measured with a barometer, whereas other gas pressures are measured with one of numerous manometer kinds.
