Do the particles of a gas get closer together or farther apart as the pressure on the gas increase?

Closer together. Your question is oddly phrased, but ends up in the same place. You might mean to ask, "Are the atoms or molecules of a gas closer to each other or farther apart if the gas is at higher pressure?" Or perhaps you are asking if the atoms or molecules in a compressed gas ("as the pressure on the gas increase (sic)") are closer or farther apart. It doesn't matter, really, because the atoms or molecules in a gas that is at increased pressure are closer together than if they were at lower pressure. Air is at lower pressure at high altitudes than at sea level. The molecules of nitrogen and oxygen are farther apart, which is why it's difficult to breathe while near the summit of a mountain.
The answer depends on whether the increased pressure is due to reduced volume or increased temperature.
When a gas is compressed, the particles are forced closer together. The temperature also rises.
To increase the pressure in a volume of gas, you can do either of two things:
- Decrease the volume. The same number of gas particles have to share a smaller space, so they must be closer together. Pressure (and temperature) rises.
- Increase the temperature. The particles move faster and try to get further apart. Since the volume is unchanged, the pressure rises. The distance between the particles is unchanged.

∙ 11y agoWhen the distance between gas particles increases, the gas is expanding and getting thinner; it will get colder, and will exert less pressure on any container that it may be in (even if we are talking about the atmosphere, which is not in a container, the ambient air pressure will decrease, if the distance between particles is increasing).

∙ 11y agowhen pressure is increased at constant temp.,the distance between the molecules decreases.by this process gas can be liquified ,if it is compressed to the critical pressure. in these type condition,always use ideal gas equation,e.i. PV=nRT.

In hot air are particles closer together?
No, farther apart.
What phase has tightly packed particles?
The phase when the particles are most closely packed together is the solid form. liquid is farther apart, and gases are even farther.
What happens to particles of matter when a liquid changes to a gas?
well, in a gas, there is pressure and temperature. the particles move farther apartThe move faster and get further apart from each other.
When the temperature increases the particles of the liquid inside a thermometer begin to move faster and what else?
Friction of the particles will increase the temperature. This is how a microwave works.
Does air pressure increase with the altitude?
No, air pressure decreases with altitude. As you go farther towards earth's surface, the weight of the atmosphere presses down with increasing force.
How are particles of a liquid different from the particles of a solid?
The particles of a solid are close together and the particles of a liquid are slightly farther apart.
In hot air are particles closer together?
No, farther apart.
As you get higher in the atmosphere does the particles get closer together or farther apart?
the particles get closer together because my class just talked about that stuff!!
What phase has tightly packed particles?
The phase when the particles are most closely packed together is the solid form. liquid is farther apart, and gases are even farther.
How can a liquid be heated?
When a liquid is heated the particles increase speed and then move farther apart. Also the liquid and bubble up.
What happens when particles of a material move farther?
When particles of a material move farther apart, it explodes.
What is the movement of particles in a solid liquid and gas?
The particles in a solid are close together.They are fixed in pace but can vibrate.The particles that make up a liquid are close together but usually farther apart than the particles in a solid are.They can slide freely past one another.The particles in gas are farther apart than particles in a liquid and solid.Gas particles move freely in any directions.
What happens to particles of matter when a liquid changes to a gas?
well, in a gas, there is pressure and temperature. the particles move farther apartThe move faster and get further apart from each other.
Why does water expand when it changes state from a liquid to a gas?
From a more physical perspective, evaporation gives the particles of water more kinetic energy and the particles are then allowed to move more and farther away from each other, resulting in expansion or increase in volume. From a more chemical perspective, the intermolecular forces holding individual water molecules closer together are completely broken when a substance becomes a gas. Without those forces holding them together, the water particles are allowed to move farther away from each other and thus expand.
What happens to the particles in a gas when the temperature increases?
The atoms or molecules of a gas will increase in kinetic energy when that gas is heated. Those atoms or molecules will exhibit an increase in their vibrational energy, and they will expand and move farther apart if they are not confined.
Why does sound travel through water easily?
sound travels farther in water because the water particles are closer together.
What happens when moist air rises?
* which of the foolowing occurs when a mass of air rises into the atmosphere? A) it becomes warmer because the particles move closer together B) it becomes cooler because the particles move closer together C) it becomes cooler because the particles move farther apart D) it becomes warmer beaouse the particles move farther apart please help and thank you :)
