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).

Is an increase in gas pressure the result of an increase in molecular collisions?
ture
What causes has pressure?
The answer depends on what kind of pressure. If you mean the pressure exerted by gasses on the walls of a container (a balloon, for example), pressure is created by the motion of the molecules of gas. Temperature and density of the molecules are factors. Higher density results in higher pressure. Higher temperature creates more molecular motion, thereby creating higher pressure.
Describe the changes in gas pressure?
The increase in solubility causes increase in pressure.
How is the pressure affected by the collision of gas particles?
The more the collisons the higher the pressure, the lesser amount of collisons the lower the pressure.
What causes pressure in closed container of gas?
collisions between the particles of gas and the container walls
Is an increase in gas pressure a result of an increase in molecular collisions?
ture
What causes a pressure in a gas?
Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.
Is an increase in gas pressure the result of an increase in molecular collisions?
ture
What is the effect of temperature and pressure on a gas?
Increased molecular activity / heat / instability
Why do you think more pressure on a gas causes the volume of the gas to decrease?
Increased pressure causes the gas molecules to come closer together, thus the volume also decreases.
What cause the pressure by gas molecules on their container?
What causes the pressure exerted by gas molecules on their container? idk
Is the pressure exerted by gas a result of the ideal gas law?
No, pressure is the result of molecular collisions by gas molecules on the walls of a container. The gas laws are merely ways of mathematically quantifying those collisions etc.

What would have happened to the gas if the molecular collisions were not elastic?
In an inelastic collision, part of the kinetic energy is absorbed by the colliding objects, and converted into heat. For an inelastic collision to occur between molecules, the energy would need to be absorbed at some lower level.
Describe the changes in gas pressure?
The increase in solubility causes increase in pressure.
Kinetic molecular theory assumptions fail at high pressure?
the kinetic energy of gas molecules is proportional to the kelvin temp of the gas
Why will a container of gas explode if it is heated?
heat causes pressure, pressure causes friction, friction causes spark, spark causes KABOOM! all in a split second
