There are 2 reasons for using high pressure oxygen in bomb calorimeter. The 1st is that we need enough oxygen for a complete combustion in a very small volume. To do that the oxidant pressure must be high. The typical air ratios in a bomb calorimeter are between 4 and 9.
The 2nd reason is that we want to measure the high calorific value of a fuel. Thus the water produced from the combustion must be in liquid form. For a certain temperature, the higher the vapor pressure, the higher the liquid water percentage. So, the higher the total pressure (25 atm), the higher the partial vapor pressure.

What is the partial pressure of oxygen in the pulmonary arteries?
The partial pressure of oxygen in expired air is 109 mmHg. Partial pressure is calculated at the proportion of oxygen in the air, so at 1 atmosphere for dry air pressure is 713 mmHg (which is 760 total pressure - 47 mmHg water vapor) and oxygen is 21% of the dry gas concentration so inspired pO2 is 150 mmHg.
Under which conditions of temperature and pressure does oxygen gas behave least like an ideal gas?
Gases show least ideal behaviour at 1- high pressure and 2- low temperature.
How gas behavior affect backpackers at high altitudes?
At high altitude the pressure is lower and the concentration of oxygen also lower.
Why can oxygen and nitrogen react together in a car engine?
Because the gases together under high temperature and pressure, and are subject to sparks.
Why does pressure kill you in bomb?
The blast effect of an explosive causes damage to the body- can include being crushed, thrown into things, having things thrown into you, etc. The high pressure can damage the soft parts of your body, such as your lungs, and you cannot breathe.
How would gas exchange be affected at the top of a tall mountain where air pressure is lower and there is less oxygen then lower elevations?
At high altitudes, atmospheric pressure is lower. Therefore, the partial pressure (partial oxygen) is lower. As partial pressure of oxygen goes down, the body's desire for oxygen goes up.

How do you can give oxygen to a patient?
There are two ways to give oxygen to a patient. You can deliver it through a face mask, connected to a tank of oxygen, or you can place the patient in a room which has its own pure oxygen atmosphere, often at high pressure as well. High pressure (technically called hyperbaric) oxygen will enter the blood even if the patient is not breathing.
What is the relationship between the air pressure and how high above the earth you are?
the higher you are, the higher the air pressure, thats why airoplanes cant go too high, there is less oxygen and more air pressure
Can high blood pressure result in less oxygen reaching heart muscle?
Yes.
Why do birds have high blood pressure?
Because they have small bodies and they need a high blood pressure to fly.The blood carries oxygen and muscles use this oxygen. Flying uses this oxygen very quickly so naturally the heart has to pump it faster. This is the same situation with humans. When Humans run their heart rate and blood pressure increase to get more oxygen to those muscles being used.
Which type of blood vessel is blood at its highest pressure?
Pulmonary arterial system has high pressure but low oxygen concentration.
What happens when oil is mixed with oxygen under pressure?
If the compression is high enough you get a diesel engine.
Oxygen crosses the plasma membrane by?
Simple diffusion process, i.e. from high pressure to low pressure

When was Bomb in the High Street created?
Bomb in the High Street was created in 1961.
What causes thin air?
Thin air is caused by low oxygen pressure at high altitudes. The lack of oxygen makes the air less dense.
