You have assumed the force exerted by molecules on the wall of container is steady in time how is this justified?

this is because the no. of collisions per sec. are very large . hence the average force or pressure delivered to the wall by a molecule per unit area is unchanging or steady with time under a given temperature.

What is the force exerted by a gas on its container?
Pressure
Which law states that a force exerted on a fluid will be transferred equally against the walls of that fluid's container?
Pascal's Law
What causes pressure in fluid's?
All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid
What is the definition of atmospheric pressure?
Air pressure is the force (weight of Earth's atmosphere) exerted on you by the weight of tiny particles of air, the air molecules above and around you. This is also referred to as "barometric pressure" (measured with a barometer) and will change with altitude or elevation. The standard pressure is 1 ATM (atmosphere), equal to 101325 pascals or 1013.25 mbar.
How do fluids exert a pressure?
air particles push against each other and against the container and these pushes create forces against their container.xD
What cause the pressure by gas molecules on their container?
What causes the pressure exerted by gas molecules on their container? idk
What causes pressure in a container?
The kinetic theory states that gas pressure is the force exerted by gas molecules impacting on the sides of the container.
What causes a gas to exert pressure when confined in a container?
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
What is the force exerted by a gas on its container?
Pressure
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.
Why would the pressure be 0 for absolutle zero?
The pressure of a gas is exerted on the walls of its container by the movement of the molecules making up the gas. The higher the temperature, the faster the particles move, increasing the pressure exerted on the sides of the container. As the temperature decreases, the movement of the gas particles slows down, reducing the pressure. At absolute zero, the gas particles would be completely frozen so that no particles would be hitting the sides of the container and the pressure exerted by the gas would be zero. This is all theoretical since absolute zero cannot yet be reached, and gas would not actually be able to have a pressure of zero.
What are the assumptions of the kinetic theory.?
Kinetic energy is the energy produced or exerted by an object in motion. The three assumptions are, that there is matter (the object exists), it is moving (in motion), and it is producing or exerting energy.
What is ferrostatic pressure?
The pressure exerted by the pressure head of liquid steel in a container at bottom surface of the container is known as ferro static pressure.
Why does liquid exert pressure on the walls of the container?
The gas molecules are moving at speeds of hundreds of metres per second. When they strike the vessel, they are accelerated in the opposite direction. The pressure on the vessel is the force exerted to cause that acceleration.
What do Pascal Vases do?
They demonstrate that pressure exerted by a liquid depends on the depth of the liquid. The shape of the container is not a factor.
Why does a gas exert more pressure if it's volume is reduced?
As the volume is decreased, the same number of molecules of air have a smaller space to move freely in. The number of collisions of molecules of air with the walls of the container per unit time increases. Since pressure is the force exerted over an area, the pressure increases.
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.
