There are many formula's for calculating the volume of air. The most basic is the ideal gas law. For this law, the answer would be V = R * T / (P * MW), where R = a constant, 10.73, T is the temperature in Rankine, which is Fahrenheit + 459.7, P is the absolute pressure in PSIA, and MW is the molecular weight, in this case use 28.5. The answer will be in cubic feet per pound of air. For example, if I had a container of air and the pressure was reading 10 pounds on the gauge, and the temperature was 70, then the formula would be as follows: PSIA = PSIG + 14.7, so PSIA = 24.7. T = 70 + 459.7, so T = 529.7. V = 10.73 * 529.7 / (24.7 * 28.5). The answer is in cubic feet per pound of air. The volume would be that of its container regardless of pressure.

The less mass in a given volume of air the what?

How are temperature and air mass related?

For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.

What happens when you decrease mass in a given volume of air?

The temperature and pressure rise.

What happens when air is compressed?

When air particles are compressed, the density is increased. There is more pressure within a region or within a container. There are more molecules in a given volume, and this can cause the air to heat up. - The pressure of the air increases, as does its temperature, as its volume decreases.

Why is hot air lighter than cold air?

Because its density is lower. At constant pressure, a given volume of hot air thus weighs less than the same volume containing colder air. ---------------------------------------- remark: This can be easily seen from the equation for ideal gases p*V = n*R*T, with p: pressure V: volume n: number of particles within the given volume R: ideal gas constant T: Temperature

Does air mass have density and pressure?

a volume of air has a mass, density, and a pressure associated with it. Although the volume's mass is constant, its density and pressure are proportional to one another.

What happens to air pressure when water vapor increases?

Atmospheric pressure is reduced with increasing water vapor because the water has a lower molecular weight than dry air. The same number of molecules occupy a given volume at a given pressure, so the total mass of water vapor laden air is lower than dry air. If you add up the weight of a column of the wet air it will weigh less than the same column filled with dry air, hence, wet air has a lower air pressure.

What are 3 factors affect air pressure?

The factors are: -The volume that the air takes up (the greater the volume the less the pressure) -The amount/number of molecules of air (the more gas the higher the pressure) -The temperature (the higher the temperature the higher the pressure) and that's it lol

Does cold air and warm air have the same air pressure?

Assuming constant volume, warmer air has more pressure.

How does liquid odor get into the air?

The liquid odor gets into the air by diffusion. Diffusion is the quality by that means the gasses tend to spread across the given volume. What is the exact reason for this phenomena is not known to me. I want to know the reason behind this phenomena. Why does gas move to fill the given volume is very easy to explain. Gas moves to make the pressure equal across the volume.

What do air density and air pressure have in common?

At a given temperature, the higher the air density, the higher the air pressure.

What is 10 percent humidity?

At any given pressure and temperatire, a volume of air can hold a certain amout of water vapour before is begins to condense out (into water droplets). 10% humidity means that the amount of water vapour in the air is 10% of what the air could hold at that pressure and temperature.

A change in can bring about a change in air pressure?

if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure

What happends to air when its heated?

In accordance with Boyle's Law, if the volume of the air is restricted, the pressure will increase. If there is no volume restriction, the air will expand.

What happens at the particle level as a given volume of air is warmed?

the particles, as they are heated start to vibrate faster giving the particles of air to heat up. the more heat put into the the volume of air the faster the particles will vibrate. The more they vibrate the more pressure the particles create by their fast vibrations. Because the particles vibrate so fast they will hit the edge of the volume container making so much pressure eventually they will break the container and go free in the air.

Why does air pressure decreases when volume increases?

Air pressure is related (among other things) to the number of atoms per unit volume. If there are less atoms per unit volume, then there are less atoms that push outward; in other words, less pressure.

How does air pressure affect the density of air?

The greater the air Pressure, the greater the Air Density at any given Altitude.

As air on the surface of earth warms the density of the air?

As air, or a gas, warms it becomes less dense, because its volume increases. This principle can be seen in action in a hot-air balloon. The warm air within the balloon envelope is so much less dense and therefore lighter than the surrounding air that the surrounding air pressure causes the balloon to rise. The relationship of temperature and pressure for an ideal gas is stated in Charles's law: "At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases." Stated as a formula, V/T = k, where V is the volume, T is the temperature, and k is a constant.

What variables can change air pressure?

Temperature, volume, height , and water vapor are variables that change air pressure.

What is amplitude related to?

I think the answer you're looking for is volume. Amplitude is what the human brains perceives as how loud or quite a sound is. The difference is volume is a perception thing as amplitude is a measureable contant. It has to to with air pressure, the more cycles of air pressure compression and decompression determians the pitch or note we hear and how great the air pressure is defines how loud we hear it and amplitude is a measurement of air pressure strength, which is related to volume.
