is it because the particles hit each other and the tyre surface??? dont rely on this answer though
--------------------------------
Gas molecules are in a state of perpetual motion and the pressure is a equivalent measurement of the total force caused by collision of the gas molecules with the wall of the tire per unit area of the tire.
'This is because the air particles are bumpinginto each other and the walls. When this happens it causes pressure on the walls because of the speed the air particles are moving
It is because of the continuous bombardment of liquid molecules on the wall.
This is one of the first things you learn in Chemistry class. PV=nRT where n and R are constants and pressure is dependent on temperature and volume. The pressure on the walls of the tire is a reflection of how energetic the molecules of air are.
they bounce and hit each other inside the cylinder and cause the pressure.
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
To expand
Yes
The constant collision of gas molecules against the inside walls of a container produces pressure which is directly proportional to the number of collisions.
Pressure and heat.
As the volume is decreased, the same number of molecules of air have a smaller space to move freely in. The number of collisions of molecules of air with the walls of the container per unit time increases. Since pressure is the force exerted over an area, the pressure increases.
The great the density the higher the air pessure.
The air molecules bouncing around off the inside of the tire. If you force something into a confined space that is usually allowed to be free it will exert pressure(Force) on th walls of it's container. An increase in tire temperature or friction will cause the air pressure to increase while colder temperatures will cause it to decrease.
