Contact between the particles of a gas and walls of the container cause pressure in a closed container of gas.
gas pressure
Collisions with container walls can cause pressure variations and create turbulence in the fluid inside the container. This can lead to mixing of different components or phase changes in the fluid, depending on the nature of the collision and the characteristics of the fluid. Additionally, repeated collisions can cause damage to the container itself, leading to potential leaks or ruptures.
A gas consists of particles, which are either atoms or molecules, which all move randomly, and independently of each other. Every time a particle bounces off the wall of a container, it exerts some degree of pressure. The total of all the particles bouncing off the walls creates the pressure that we observe.
On the molecular level pressure is caused by individual gas molecules interacting with the surfaces of a container. Pressure is defined as force per unit area, so in the most basic level pressure can increase with an increase in force applied to the container or a decrease in area the molecules are interacting with. The decrease in area can be from a smaller container, or an increase in force can be from an increase in the velocity of the molecules. This increase in velocity is usually due to an increase in energy (typically heat).
A decrease in gas pressure in a closed container could be caused by a decrease in temperature, which reduces the average kinetic energy of the gas molecules, leading to fewer collisions with the container walls. It could also be caused by a leak in the container allowing gas to escape, or by a chemical reaction that consumes gas molecules.

gas pressure
Gas pressure in a closed system is caused by the constant collisions of gas molecules with the walls of the container. These collisions create a force that exerts pressure on the walls of the container. The more frequent and vigorous the collisions, the higher the gas pressure.
The weight of the air The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.

The number and vibration of the molecules that make up the gas cause the pressure.

Gas pressure is caused by gas molecules zipping around and bumping into things. These molecules have kinetic energy defined a 1/2 the mass times the velocity squared. Increasing temperature increases the speed that the molecules zip around - so the pressure increases (hot soda can for example has more pressure than a cold one).
High pressure is stronger. Pressure is caused by the gas particles in a container hitting the sides of said container. At high pressure, the particles hit the sides of the container much more and therefore are pushing harder on the sides.
An increase in temperature of a gas kept at constant volume is due to the gas particles gaining kinetic energy. As temperature rises, the average speed of the gas particles increases, causing more collisions with the container walls and resulting in a higher pressure. This increase in pressure is caused by the gas particles hitting the walls more frequently and with more force.
