Does the pressure of a gas depend on the type of gas?
So pressure is proportional to the number of moles of gas, not the mass of the gas. If you replace a given gas with one with double the molecular weight, for n to be the same, the mass of the replacement gas has to be double the mass. Yet the pressure is the same. Pressure is not dependent on mass.
What does the pressure exerted by a gas depend on?
Pressure depends on the force exerted by the gas on the container divided by the total surface area of the container.
Why do gas exert pressure short answers class 9?
The pressure exerted by a gas is due to the random motion of particles in the gas. Gases have weak intermolecular forces and the particles are in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exert pressure on the gas.
Why do you think the pressure is exerted by the gas on the walls of the container in all directions?
The kinetic molecular theory makes it easy to see why a gas should exert a pressure on the walls of a container. Any surface in contact with the gas is constantly bombarded by the molecules. At each collision, a molecule moving with momentum mv strikes the surface.
Is the pressure exerted by a gas depends on its molar mass?
Originally Answered: Does the pressure of gas depend upon the mass of gas? Not on the molar mass, only on the amount of molecules. For an ideal gas, pV=nRT, or p = nRT/V. The same amount of heavy or light molecules (n) will result in the same pressure.
What does gas pressure depend on Quizizz?
The pressure depends on the type of gas in the balloon. What happens to the temperature of a gas when it is compressed? The temperature increases.
Why do gases exert more pressure on the walls of the container than the solids Class 9?
In gases, the particles move randomly at high speed and they collide with each other and also with the walls of container. Thus, they exert . more pressure on the walls of container than solids.
Why does a gas exert pressure on the walls of the container class 9?
The moving particles in a gas collide with each other and also with the walls of the container and due to these collisions, Gases exert pressure on the walls of the container.
What property of gas is defined as the force exerted by the gas to the walls of its container?
At microscopic level, pressure is the force exerted by the gas molecules on the wall by virtue of momentum change during their elastic collision with the wall atoms.
What kind of pressure is exerted on the walls of the container?
The force exerted on the walls of the container is called thrust. Fluids exert the thrust normally on the surface in contact. S.I. the unit of pressure is N/m2 or Pascal.
Does the pressure depend on the mass of the particles?
The value of pressure and temperature does not depend on the amount of gas used in the measurement. The mass of the gas, on the other hand, does depend on the volume.
What would not cause an increase in the pressure of a contained gas?
Which of these changes would NOT cause an increase in the pressure of a contained gas? The volume of the container is increased.
Why does increasing the temperature of a gas increase the pressure it exerts Quizizz?
Why does the pressure inside a container of gas increase if more gas is added to the container? There is an increase in the number of collisions between particles and the walls of the container. There is an increase in the temperature of the gas. There is a decrease in the volume of the gas.
Why does a gas exert pressure Why does a gas fill a vessel completely Why are gases so easily compressible whereas it is almost impossible to compress a solid or a liquid?
(c) Gases are easily compressible as they have large inter-molecular spaces. The gas particles can come closer when external pressure is applied on gases.
Do liquid and gases exert pressure on the walls of container in all direction give an example to justify your answer?
For example-If we take a plastic bottle and drill four holes around near the bottom of bottle at the same height. After filling the water in that bottle, we observe that water comes out of the holes and falls at the same distance. This shows that liquid exerts pressure on the walls of container in all directions.
When gas exerts pressure on its container the pressure is quizlet?
Gas exerts pressure on the walls of its container because the particles collide with the wall. What happens to the temperature in gases? If the gas gets hotter, the pressure will be bigger. If the gas gets cooler, the pressure will be smaller.
Why do gases exert pressure on a surface?
Gas pressure is caused by the force exerted by gas molecules colliding with the surfaces of objects (Figure 1). Although the force of each collision is very small, any surface of appreciable area experiences a large number of collisions in a short time, which can result in a high pressure.
How is pressure affected by force?
Pressure equals force divided by area (P=FA P = F A ). The equation shows that pressure is directly proportional to force, but inversely proportional to area. At a constant area, pressure increases as the magnitude of the force applied also increases.
Why do the gases exert more pressure on the walls of the container than the solids Class 9?
In gases, the particles move randomly at high speed and they collide with each other and also with the walls of container. Thus, they exert . more pressure on the walls of container than solids.
On what factors the pressure exerted by the liquid depends on?
The correct option is C height of the liquid column. The pressure exerted by a liquid depends on: density of the liquid. acceleration due to gravity.
Does a heavier gas exert more pressure?
Although the collisions are less frequent, the heavier gas has more momentum. Because of this, it strikes the sides of its container with more force, albeit less often. Supposedly, this makes up for the lower collision frequency in the heavier gas. This is why both gases have the same pressure.
Does mass of a gas increase with pressure?
In a very thin horizontal layer of gas, the pull of gravity on the layer itself hardly influences its pressure. But if there is a 'column' of gas above the layer, the weight of the column will indeed increase – or even be wholly responsible for – the pressure in the layer.
How does the pressure of gas in a closed container compare to the volume of the container?
The volume of a gas and its pressure are inversely related. Decrease the volume, and the pressure increases. This relationship is called Boyle's law in honor of Robert Boyle who first observed that increased pressure lowered volume.
Why does the pressure inside a container of gas increase if more gas is added to the container?
Why does the pressure inside a container of gas increase if more gas is added to the container? Correct! As the number of particles increases in a container there are more collisions of the particles with the sides of the container which increases pressure.
Why does gas fill completely the vessel?
Gases have a negligible intermolecular force of attraction between the particles of gas. As a result, the random motion of particles in all directions is experiencing in the vessel. Hence, the gas fills the vessel in which it is kept.
Why are gases easily compressible whereas it is almost impossible to compress a solid or a liquid?
(c) Gases are easily compressible as they have large inter-molecular spaces. The gas particles can come closer to each other when external pressure is applied to gases. On the other hand, it is almost impossible to compress a liquid because the intermolecular spaces in liquids are small.
Why do the gases exert more pressure on the walls of the container than the liquid?
Note- Gas exerts more pressure than liquid on the wall of the container in which they are kept because they have less intermolecular force than liquid. The pressure exerted by the gas is due to the spontaneous movement of the ions in the air.
When gas exerts pressure on the container the pressure is?
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.
When gas exerts pressure on its container the pressure is?
A gas exerts uniform pressure in all directions on the walls of the container in which it was enclosed. It is because of the random motion of the gaseous particles. We know that gaseous particles are very far from each other. So, the intermolecular force between them is very weak.
Is the pressure of gas independent of its temperature?
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law).
