Do gases have the same volume as the container in which they are contained?
Because gases expand to fill their containers, it is safe to assume that the volume of a gas is equal to the volume of its container. The difference between the volume of a gas and the volume of the liquid or solid from which it forms can be illustrated with the following examples.
How is it possible that all gases have the same volume at the same temperature and pressure?
If temperature and pressure are kept constant, then the volume of the gas is directly proportional to the number of molecules of gas. If the temperature and volume remain constant, then the pressure of the gas changes is directly proportional to the number of molecules of gas present.
What is the relationship between the size of the container of a gas and its volume and pressure?
When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since P and V are inversely proportional, a graph of 1/P vs. V is linear.
What happens to the volume of a gas in a container if the container is compressed?
During compression, the volume (V) of a gas decreases. When this happens, the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant, reducing the temperature (T) also causes the gas to compress.
Why do all gases have the same molar volume at STP?
As all gases that are behaving ideally have the same number density, they will all have the same molar volume. At STP this will be 22.4 L. This is useful if you want to envision the distance between molecules in different samples.
Why is volume of gas equal to volume of container?
As we know that molecules have high intermolecular space between their particles and less intermolecular force of attraction between particles so they are very lossely packed. They are fluids in nature. so volume of gas is always equal to volume of container in which it held.
Do all gases have the same mass at STP?
Mass Density of a Gas This is the mass of the gas relative to the volume of the gas. Because gases that are behaving ideally under the same conditions (temperature, pressure) all have the same number density, they will all have different mass densities since different gases have different masses per particle.
Do all gases have the same reactivity at STP?
The standard molar volume is 22.4L. B. All gases have the same mass. All gases have the same reactivity.
What is the relationship between the number of particles and volume of the chamber when the temperature and pressure are held constant?
inversely proportional
The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro’s law).
What is the relationship between the temperature and the volume of a gas?
Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.
What happens if you put gas in a container?
“As temperature rises, gasoline expands, and in order to equalize the pressure, the container would release pressure by allowing gas vapour to escape.” That same expansion happens in your car’s gas tank, but it’s designed to release the vapours safely to the outside, Filipovic said.
When you decrease the size of the container that a gas is in the gas will exert more pressure on the container?

| According to _____, if you decrease the volume of a container of gas and hold the temperature constant, the pressure of the gas will increase | Boyle’s Law |
| According to ______, the volume of a gas increases with increasing temperature, as long as pressure does not change | Charles’s Law |
Can two or more gases in one container have different volumes?
I know that technically two or more gases in one container should have different volumes. But when you imagine the gas molecules being mixed together, it look sorta like the two gases have the exac… Stack Exchange Network
What is the difference between a gas cylinder and a sphere?
Spheres are more efficient than cylinders if you just care about minimizing the mass of the tank to hold a certain amount of pressurized gas. But cylinders are easier to pack together. So it’s a trade-off between efficiency and practicality. Hiring CS majors for internships and entry-level roles.
Do all gases have the same volume and temperature?
In short, each component of a mixture of gases stored in a given container shares the same volume and temperature and may (or may not) have different partial pressures and number of moles. $\\begingroup$ Wait even partial pressure of ideal gas depends on their mole ratio which is volume ratio.
What happens when a gas is trapped in a cylinder?
An example of this is when a gas is trapped in a cylinder by a piston. If the piston is pushed in, the gas particles will have less room to move as the volume the gas occupies has been decreased. Because the volume has decreased, the particles will collide more frequently with the walls of the container.
