How does pressure affect volume?
With the ideal gas law PV=nRT, if n (number of molecules, R(gas constant) and T (temperature) are fixed, then the product of P (pressure) and V (volume) is also constant. So. Pressure and Volume are inversely related. If pressure goes up, volume must go down and if pressure goes down, volume must increase. The same goes with increasing or decreasing volume.
A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
What source of heat is compression?
The three variables are P, V and T. n doesn't change. R is a constant. If gases were perfectly compressible, the volume would decrease inversely proportional to the increase in pressure. There would be no reason for the temperature to increase. But gases are not perfectly compressible. V does not decrease linearly with increases in P. In order to keep the Ideal Gas Law in balance, T has to increase. or Because the molecules of the gases are being mechanically compressed or being pushed together, causing them to rub tightly and trying to get them into a smaller piece of real estate than they were intended to have. or when you compress a gas, you have to do work on the gas to compress it...this work results in greater kinetic energy in the gas, which causes molecules to move faster, which increases the temp.
What causes the pressure that a gas exerts on the wall of its container?
Kinetic theory explains the pressure that a gas exerts on the walls of its container. This describes elastic collisions between the atoms or molecules in the gas with the container's walls, which collectively exert a measureable pressure.
Which gas helps the foam that fire fighters use?
In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution. Larger systems use a dedicated air compressor and compresses regular air from the atmosphere.Smaller systems can use any inert compressed gas such as Carbon Dioxide (CO2), Compressed Nitrogen (N2) or smaller tanks of compressed regular air.The simplest, most efficient and least expensive way of producing foam is with a portable foam eductor. These foam systems use regular hand lines and an eductuor 100 feet from the end of the nozzle. The eductor siphons foam solution from a tank or drum using the "Venturi" principal. When the foam solution reaches a standard fog nozzle, water pressure and the broken stream produced by the nozzle introduce air into the foam solution.There are other forms of nozzles that introduce water using the "Venturi" effect that are not user adjustable like a fog nozzle.The quick easy answer is regular air is used most commonly in fire fighting foam however CO2 and N2 can be used depending on the design of the system used.In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution.

How is pressure affected when a gas is compressed?
When a gas is compressed, its volume decreases while the number of gas molecules remains the same. This leads to the gas particles being more concentrated in a smaller space, resulting in an increase in pressure according to the ideal gas law, which states that pressure is inversely proportional to volume.
What happens to the density of air when it is compressed into a tire?
When air is compressed into a tire, its density increases because the same amount of air molecules are now packed into a smaller volume. This increase in density helps maintain the tire's pressure and support the vehicle's weight.
Can the particles in gas be compressed into smaller volume?
Yes, particles in a gas can be compressed into a smaller volume by reducing the space between them. This will increase the pressure of the gas as the particles are forced closer together.
What happens when a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
What term best describes a gas under greater than atmospheric pressure?
The term "compressed gas" best describes a gas under greater than atmospheric pressure. This typically refers to gases that have been compressed into a smaller volume using pressure vessels.
What happens to the air pressure when a sealed bag is compressed?
When a sealed bag is compressed, the air inside the bag is forced into a smaller volume, which increases the air pressure. According to Boyle's Law, the pressure of a gas is inversely proportional to its volume when temperature is held constant. Therefore, as the volume decreases due to compression, the air pressure within the bag rises until the bag reaches its elastic limit or the pressure equalizes with the surrounding environment.
Can gas particules cannot be compressed into smaller spaces?
Gas particles can be compressed into smaller spaces because they have a lot of empty space between them. When gas particles are compressed, their volume decreases due to the reduction in this empty space, resulting in an increase in pressure.
What happens when a fluid at constant pressure is moved to a smaller areas?
Force increases.
What happens when a fluid at constant pressure is moving to a smaller area?
Force increases.
How can gas be compressed effectively?
Gas can be compressed effectively by reducing its volume while increasing the pressure applied to it. This can be achieved by using a compressor, which forces the gas into a smaller space, causing its molecules to come closer together and increasing its pressure.
Why does the pressure of a gas rise when it is squashed into a smaller space but it's temperature is kept the same?
When a gas is compressed into a smaller volume while maintaining a constant temperature, the molecules are forced closer together. This increases the frequency of collisions between gas molecules and the walls of the container, leading to a rise in pressure. According to Boyle's Law, for a given amount of gas at constant temperature, pressure and volume are inversely related; thus, reducing volume results in increased pressure.
What happens the density of a gas as it is compressed?
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
