The air pressure inside a jar is related to the number of air molecules present. When there are more air molecules in the jar, the pressure increases due to more collisions with the walls of the jar. Conversely, fewer air molecules result in lower pressure.
You could increase the air pressure inside a bag by decreasing the volume of the bag, adding more air molecules to the bag, or increasing the temperature of the air molecules inside the bag.
The air pressure inside the bottle will increase as more air is filled up inside. This is because the air molecules are compressed, resulting in higher pressure.
Adding more air molecules to a balloon increases the number of collisions between the molecules and the balloon walls, thereby increasing the pressure inside the balloon. This increase in air pressure causes the balloon to expand until the pressure inside matches the pressure outside.
The pressure inside a balloon is created by the air molecules contained within the balloon pushing against the walls of the balloon. As more air is blown into the balloon, the number of air molecules increases, leading to a higher pressure inside the balloon.
When you heat up the air inside a can, the molecules gain kinetic energy and move faster, increasing the pressure inside the can. When you quickly cool the can by submerging it in cold water, the air molecules lose energy and slow down, causing a decrease in pressure inside the can. The external atmospheric pressure then crushes the can as it is now greater than the pressure inside the can, resulting in the can collapsing.

This is the effect of the pressure.
Air density and air pressure are inversely related. As air density increases, air pressure also increases because there are more air molecules in a given space exerting force on the surroundings. Conversely, when air density decreases, air pressure decreases as well due to fewer air molecules exerting force.
Air molecules inside a sealed box move around randomly and collide with the walls of the box. These collisions create a force that exerts pressure on the walls of the box. The more molecules and the faster they move, the greater the pressure they exert.
The pressure inside the lungs decreases as the ribcage moves out and up. Air from outside basically gets pushed in by other air molecules due to the pressure gradient (air moves from a high pressure to a low pressure)
You can increase the air pressure inside the bag by reducing the volume of the bag or adding more air molecules to it. This can be done by squeezing the bag to decrease its volume or blowing air into the bag to increase the number of air molecules present inside.

Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
