The average distance between oxygen molecules at Standard Temperature and Pressure (STP) is approximately 3.3 nanometers.
As distance from Earth increases, the atmospheric pressure decreases. This is because there are fewer air molecules present at higher altitudes, leading to lower pressure.
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.
As altitude increases, pressure decreases, so boiling point decreases, so the liquid would boil at a lower temperature and would not be able to get as hot and remain a liquid. As pressure is increased, boiling point increases, meaning the liquid could get hotter than normal and remain a liquid.PV=nRT - pressure x volume = the number of moles x constant x temperature
A constant volume gas thermometer is a thermometer that uses the variations of pressure in gas at different temperatures to measure the temperature. A liquid can then be put into tubes, and rather than measuring the distance of a small quantity, the distance between two parts of the curving tube are used to measure the temperature.
Particle speed is not directly related to the distance between particles. The speed of individual particles in a substance is determined by factors like temperature and pressure. However, the average speed of particles in a substance can affect the distance between particles indirectly by influencing the pressure exerted by the substance.
Yes. This can be none by drcreasing the temperature or, if the substance is not above its critical point, by increasing the pressure.
The weight of the air The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.

As distance from Earth increases, the atmospheric pressure decreases. This is because there are fewer air molecules present at higher altitudes, leading to lower pressure.
The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.
Temperature is an indirect measurement of a system's molecule's average kinetic energy (KE). As the temperature of a system increases, so does the KE of the molecules. This causes the molecules to move farther apart. You can see this most easily in an old (not digital) thermometer.
There is really no standard distance from the sound source where the sound pressure level (SPL) is measured.
The mean free path of a water molecule is the average distance it can travel between collisions with other molecules. In the case of water at room temperature and pressure, the mean free path is typically on the order of micrometers to millimeters. This can vary depending on the specific conditions of temperature and pressure.
The distance of a planet from the Sun significantly influences its temperature and atmospheric pressure. Generally, planets closer to the Sun receive more solar radiation, leading to higher temperatures, while those farther away tend to be cooler. This temperature variation affects atmospheric pressure, as warmer air can hold more moisture and leads to higher pressure, while cooler air results in lower pressure. Consequently, the interplay between distance, temperature, and pressure shapes each planet's climate and atmospheric conditions.
The force of air is determined by the atmospheric pressure, which decreases with increasing altitude above sea level due to the decreasing density of air molecules. Additionally, temperature affects air density, with warmer air being less dense than cooler air. Overall, the combination of temperature and altitude influences the force of air pressure exerted at a specific location.

It doesn't. The equation for mean free path is: mfp = 1 / [sqrt(2)*n*pi*d^2] In the above equation, n is the number of molecules per unit volume, and d is what is known as the collision diameter (the distance between the centers of the two colliding molecules). Thus, there are only three variables which affect mean free path: number of molecules, volume, and collision diameter. Volume can be changed by a change in temperature, but this question assumes constant volume (meaning pressure will change as temperature changes). As long as the amount of gas is unchanged, the mean free path will be unaffected by changes in temperature. This is a wrong answer. The collision diameter decreases with the increase of temperature.
