You need some sort of an instrument. Most of us just use a pressure gauge, although you could do it empirically--you could throw the end of the hose in water, and if bubbles came out you would know the gas pressure is at least as high as the water pressure--which is 15psi since the 15psi atmosphere is pressing down on the water.
What else can I help you with?
Equal volumes of nitrogen and oxygen at the same temperature and pressure would?
If equal volumes of nitrogen and oxygen are at the same temperature and pressure, then both (the nitrogen and oxygen) will contain the same number of particles
How many moles of nitrogen and oxygen are in a cubic foot?
To determine the number of moles of nitrogen and oxygen in a given volume like a cubic foot, you would first need to know the pressure and temperature of the gas. Then you can use the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature. So without knowing the pressure and temperature, it is not possible to determine the number of moles of nitrogen and oxygen in a cubic foot.
Why must nitrogen be used only with oxygen under pressure?
Nitrogen should be used with oxygen under pressure to prevent the development of decompression sickness. When breathing high-pressure oxygen for a period of time, the body accumulates excess nitrogen which can form bubbles in the blood when pressure is reduced. This can result in decompression sickness, also known as "the bends."
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.
what gas experiences a greater change in solubility per unit pressure oxygen or nitrogen?
Oxygen generally experiences a greater change in solubility per unit pressure compared to nitrogen. This is due to oxygen's higher solubility in water, driven by its ability to form stronger interactions with water molecules. Nitrogen, being less soluble and having weaker interactions, shows a smaller change in solubility with pressure. Thus, under increased pressure, oxygen dissolves more significantly than nitrogen.
Why is pressure and density important when giving the density of oxygen and nitrogen?
Pressure and density are essential because they affect the volume that a gas occupies. When providing the density of gases like oxygen and nitrogen, the pressure and temperature at which the density is measured must be specified to accurately represent the physical state of the gas. Changes in pressure and temperature can significantly impact the density of gases.
Is oxygen free nitrogen pressure affected by temperature?
Yes, the pressure of oxygen-free nitrogen is affected by temperature. As temperature increases, the pressure of a gas also increases if the volume and amount of gas are constant, according to the ideal gas law. Conversely, as temperature decreases, the pressure decreases.
. A mixture of oxygen hydrogen and nitrogen gases exerts a total pressure of 282 kPa. If the partial pressures of oxygen and hydrogen are 110 kPa and 106 kPa respectively what is the partial pressure?
Total pressure = ppO2 + ppH2 + ppN2ppN2 = Total pressure - (ppO2 + ppH2)ppN2 = 282 kPa - (110+106 kPa) = 282kPa - 216kPappN2 = 66 kPa = partial pressure of nitrogen
What is the partial pressure of oxygen if the partial pressures of the nitrogen and carbon dioxide are 100 kPA and 24 kPa respectively?
To find the partial pressure of oxygen, you can use Dalton's Law of Partial Pressures, which states that the total pressure is the sum of the partial pressures of all gases in a mixture. Assuming the total pressure is the sum of the given partial pressures, you can calculate it as follows: Total Pressure = Partial Pressure of Nitrogen + Partial Pressure of Carbon Dioxide + Partial Pressure of Oxygen. If we denote the partial pressure of oxygen as ( P_O ): Total Pressure = 100 kPa + 24 kPa + ( P_O ). Without the total pressure, we cannot determine the exact value of the partial pressure of oxygen. However, if the total pressure is known, you can rearrange the equation to solve for ( P_O ) as ( P_O = \text{Total Pressure} - 124 kPa ).
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
What are the three elements that exist as a gas at room temperature and pressure?
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.
What to use to make nitrogen oxide?
Nitric oxide (NO) can be made by reacting nitrogen gas (N2) with oxygen gas (O2) in the presence of a high temperature and pressure. Nitrogen dioxide (NO2) can be formed by the further oxidation of NO.
