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.
Contact between the particles of a gas and walls of the container cause pressure in a closed container of gas.
Gas pressure is caused by the gas molecules moving back and forth.You can increase the gas pressure by putting gas into a container with hard walls, i.e. not flexible as in a balloon, and doing one or more of the following:Increasing the amount of gas (pumping gas in)Increasing the temperatureReducing the volume (as in a piston)For more details, read about the "ideal gas law".
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).
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 atmosphere exerts pressure on various objects on the earth's surface. Air pressure is generally caused by the collision of the gas molecules with one another.
The change in phase is called evaporation. It can be caused by heating or by a change in air pressure.
Resultant force of all combined collisions with the walls of the container.
The fizz is caused by the carbon dioxide gas dissolved under great pressure into the soft drink. Opening the top releases the pressure and the gas begins to escape in a mass of bubbles.
