Explain why pressure increases as a gas is compressed into a smaller volume?

PV=nRT
Where:-
P=pressure
V=volume
n=number of moles
R=gas constant
T=temperature
n,R and T all remain constant. So if volume is decreased, in order for the right hand side to remain a constant value, the value for pressure must increase.

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.

Explain what hppens to air pressure as you move away from the earths surface?
Pressure increases as you get closer to earth.
What happens when a fluid at constant pressure is moved to a smaller areas?
Force increases.
What happens when a pressure greater than atmospheric pressure is applied on pure water?
It is compressed and occupies a smaller volume.
When area reduces pressure increases or decreases?
Pressure is force divided by area, i.e. P = F / A. So the smaller A is, the larger P is. That is, when area reduced pressure increases.
What happens when a fluid at constant pressure is moving to a smaller area?
Force increases.
What happens when a fluid at constant pressure is moved at a smaller area?
Force increases.
Why does pressure of gases when you put it in a smaller container the pressure rises?
According to Boyle's law, the pressure of a gas depends on its volume, so if you lower the volume, the pressure increases.
When the chest cavity become smaller the air pressure inside the chest cavity become?
Increases .
How does the change in the volume affect the density of solids liquids and gases?
the change in volume affects the density of solids, liquids , and gases by when the volume of a liquid , solid . or gas expands the density changes.
What happens to the gas volume at a given pressure?
The gas takes on the size and shape of the container it's in. So if you make the volume of the container smaller (compress it) the volume of the gas is smaller as well. However, this comes at a higher pressure exerted, so there is no spontaneous mass creation.Well, by definition, compress means "to make smaller; to press or squeeze together; or to make something occupy a smaller space or volume." Therefore, the very word "compress" implies a decrease in volume. So if you wanted to know what happens when you compress a gas, you are squeezing it into a smaller space, or decreasing the volume.If you were to let the gas maintain a constant temperature as you compress it, then pressure would increase. If you were to let the gas maintain a constant pressure, then temperature would decrease.If you were to rephrase your question to "what happens to the volume of gas if put under pressure," then the gas' volume would decrease. For the temperature to remain constant and the pressure to increase, a gas must decrease in volume to occupy a smaller area.
As the magnification used in microscope increases is more or less illumination needed Explain your answer?
As the magnification increases, more light is needed. This is because the size of the hole of the lens is smaller.
Why does density increase when a gas is compressed?
There will be the same amount of gas but in a smaller space. Density is mass/volume So as volume decreases and mass is constant, the density increases.
