A gas exerts pressure because it pushes on the walls of its container and the other gas molecules in the sample.
Molecular collisions between the gas molecules and those in the walls of the container are the means by which a force is exerted. The gas molecules move so fast that all of the collisions average out over time to create a constant pressure.
Although gasses are usually never visible, they still have a mass. Gasses bounce around at different temperatures and pressures. Lets say you're blowing up a balloon, when you blow into the balloon you are releasing gasses into the balloon. The gasses begin bouncing around hitting the walls of the balloon at really high speeds. As you blow more air, it increases the number of gas molecules and therefore, how many are bouncing around, hitting the sides.
Gas exerts pressure because each molecule of the gas is zinging around with kinetic energy within a given area. When these molecules hit another molecule, such as the solid walls of a container, the kinetic energy is transferred from the gas molecule to the molecules of the wall and is recorded as pressure.
The atoms that make up a gas are in constant, random motion. This means that at all times, atoms of that gas are colliding with the walls of whatever container it's stored in, whether it's a balloon or other vessel. The average of all the collisions with the sides of the container is that gas's pressure. Heat up the container and the collisions increase because the atoms of the gas have more energy, and the pressure goes up.
How much pressure a gas exerts depends on the number of gas particles in a given space and how fast they are moving. The more gas particles there are and the faster they are moving, the greater the pressure they create.
Because the molecules in the gas are constantly flying and zipping around every
which way in all kinds of random directions at all kinds of random speeds. There are
always some of them bumping into the walls of the container, and all of those little
individual molecular forces add up to form what we perceive as pressure.
The rapid movement of particles is what causes the pressure. The amount of pressure a gas exerts is determined by how hard the gas particles slam against the side of the container. The harder the particles push, the more the pressure.
This is because all the molecules of a gas are in motion. This motion causes them to hit the sides of the container and the effect of these collisions is felt as the pressure exerted by the gas.
gases disperse to fill whatever container they occupy since gases are composed of Matt which takes up space.
Any gas has also a mass.

Compressing a gas means increasing the pressure on the gas and according to Boyle's law pressure is inversely proportional to the volume of a given amount of a gas(at constant temperature) . Therefore increasing the pressure (compression) of the gas reduces the volume of the gas.
A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.
The arrangement becomes more tight and compact whereas if the gas is not under high pressure the gas will take up more space. The arrangement becomes more tight and compact whereas if the gas is not under high pressure the gas will take up more space.
If the height of the mercury column in the leveling bulb is 30mm greater than that in the gas buret and atmospheric pressure is 670mm, what is the pressure on the gas trapped in the buret?
they are made by rocks and gas pressure and gas
Gas Pressure
It is unclear what you are asking. A contained gas will always exert pressure, but it would be incorrect to state that gas is pressure.
The pressure of each gas in a mixture is called the partial pressure of that gas.
The pressure of gas has nothing to with ATP. However, the pressure of gas at STP, or Standard Temperature Pressure is 0 degrees Celsius and pressure is 1 ATM.
is motions of gas particles are related to the pressure exerted by the gas
The pressure of a gas increases with an increase in temperature.
The pressure of a gas increases with an increase in temperature.
The pressure increase.
If the gas is contained at a constant volume, the pressure increases. If the gas is not contained, the pressure remains the same or drops.
Once pressure reaches vapor pressure, gas will liquify at that temperature.
