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 is the volume of 1 pound of air?
The volume of 1 pound of air can vary depending on the temperature, pressure, and density of the air. At standard temperature and pressure (STP) conditions of 0 degrees Celsius and 1 atmosphere pressure, the volume of 1 pound of air is approximately 13.1 cubic feet. However, if the air is at a different temperature or pressure, you would need to use the ideal gas law equation (PV = nRT) to calculate the volume.
What is a what is air pressure measured with?
Air pressure can be stated in different ways. kpa is kilopascals, the metric system psi is pounds per square inch in the standard system 1 bar is equal to the air pressure at sea level 1 kpa= about 7 psi 15 psi = about 1 bar
What happens when gas loses its energy?
If you allow the gas to contract, it will shrink in volume as you cool it and may also drop in pressure if the surroundings will allow it. Changes in pressure and volume can translate to work being done on or by the system. If you keep the volume constant it will only drop in pressure while cooling and no work will occur.
Does the air inside a fully pumped basketball have a lower or higher pressure than the air outside?
the higher pressure is due to a greater number of gas particles per unit volume inside the ball then in the surrounding air.
How to Convert kg's of air to cubic meters of air at 6bar?
Air at 10 celsius and 1 bar(absolute) has density 1.25 kg/m3. By 6 bar do you mean gauge or absolute pressure? To apply a pressure factor you must use absolute, ie the pressure above a vacuum. Normal atmospheric conditions are 1 bar (abs). If you mean 6 bar(abs) the density becomes 6 x 1.25 = 7.5 kg/m3. On the other hand if you mean 6 bar (gauge) this is 7 bar (abs) and the density would be 7 x 1.25 =8.75 kg/m3. Either way, you just divide the weight of air in kg by the density to get the volume.
How much bar needed to convert air to liquid under pressure?
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
Volume of 10000 liters of air at 2 bar pressure?
Volume of 10000 Litres is suprisingly enough exactly, not more or less than: 10,000 liter or 10 cubic metresUse pV=nRT! Make sure you convert the pressure into Pascals.
What is the Physical quantity measured in bar?
Pressure is the physical quantity measured in bar.
What is pressure volume relations for air?
The pressure-volume relationship for air is described by Boyle's Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. This means that as the volume of a container holding a sample of air decreases, the pressure of the air inside will increase, and vice versa. Mathematically, this relationship is expressed as P1V1 = P2V2, where P represents pressure and V represents volume.
Do scuba divers breath pure oxygen?
Believe it or not, we can die from too little oxygen AND too much oxygen. This concept involves partial pressures. If we first consider using standard air (i.e. 20% Oxygen and 80% Nitrogen): (1 bar = 1 kilogram of pressure per square centimetre) At the surface - Total Pressure of air = 1 bar - Pressure of Oxygen = 0.2 bar - Pressure of Nitrogen = 0.8 bar At 10m - Total Pressure of air = 2 bar - Pressure of Oxygen = 0.4 bar - Pressure of Nitrogen = 1.6 bar At 20m - Total Pressure of air = 3 bar - Pressure of Oxygen = 0.6 bar - Pressure of Nitrogen = 2.4 bar At 30m - Total Pressure of air = 4 bar - Pressure of Oxygen = 0.8 bar - Pressure of Nitrogen = 3.2 bar At 40m - Total Pressure of air = 5 bar - Pressure of Oxygen = 1.0 bar - Pressure of Nitrogen = 4.0 bar At 50m - Total Pressure of air = 6 bar - Pressure of Oxygen = 1.2 bar - Pressure of Nitrogen = 4.8 bar At 60m - Total Pressure of air = 7 bar - Pressure of Oxygen = 1.4 bar - Pressure of Nitrogen = 5.6 bar At 70m - Total Pressure of air = 8 bar - Pressure of Oxygen = 1.6 bar - Pressure of Nitrogen = 6.4 bar It is at the partial pressure of 1.6 bar (which occurs at 70m where oxygen becomes toxic. That is why most dive organisations recommend 50m as a maximum for recreational diving. However, if pure oxygen is used: At surface - Pressure of Oxygen = 1 bar At 10m - Pressure of oxygen = 2 bar The oxygen has already become toxic! Hope that answers your question. The concept is called "partial pressures" and "oxygen toxicity" if you want to research more on a search engine.

How much does the air pressure decrease in bar from sea level to an altitude of 1200 meter?
At sea level, the average air pressure is about 1 bar. As you increase in altitude, the air pressure decreases. On average, the air pressure decreases by about 12% for every 1000 meters of elevation gain. Therefore, at an altitude of 1200 meters, the air pressure would be approximately 0.88 bar.
What is the mass of air at 7 bar?
Air has a density of 1.2 kilogram per cubic metre at sea level and at 20 degrees C. You would need to know the volume of the container. 7 bar is 7 times normal atmopheric pressure
What is one property of air?
Air is compressible, meaning its volume can change in response to changes in pressure.
What is an example of voume and pressure of an object?
An example of volume and pressure of an object would be a balloon. When you blow air into a balloon, you are increasing its volume which in turn increases the pressure inside the balloon. If you release the air from the balloon, the volume decreases and the pressure decreases as well.
