i wonder if "gas pressure > out pressure" this can be possible. if so how?
Copy that...voko said:Ahem. What?
It is not a translation problem, it is a description problem. You only gave us part of one sentence! Please write a much longer description of the problem and translate that.jukzzhd said:sorry for bad translation. that was all i can do
No, that is not true. At every free air-water interface (every lake, river, sea) the pressures are exactly equal. Is there any boiling?jukzzhd said:as we know when the gas pressure of a liquad is equal with the outside pressure, liquid starts to boil

Not vapor, vapor pressure. We're talking about what is happening in the liquid and if/why it turns to gas. Saturation pressure and vapor pressure are equal here.voko said:I am not sure I follow this. You said the question was about vapor. If vapor pressure exceeds ambient pressure, then it just expands, possibly part of it condensing or even solidifying in the process.
But then you gave an example involving a liquid, not vapor. What are we really discussing here?
Heat and cool several times in a smooth container which does not promote bubbling to increase probability.Khashishi said:What about super-heated water? I heard if you microwave deionized water in a clean cup you can get this.
Yes, gas pressure can exceed atmospheric pressure in certain situations. Atmospheric pressure is the pressure exerted by the weight of the air above us, and it can vary based on altitude and weather conditions. Gas pressure, on the other hand, is the force exerted by gas molecules colliding with the walls of a container. If the temperature and number of gas molecules inside a container increase, the gas pressure will also increase and can exceed atmospheric pressure.
Gas pressure can exceed out pressure due to a variety of factors. These include increasing the temperature of the gas, increasing the number of gas molecules present, and decreasing the volume of the container. Additionally, chemical reactions, such as combustion, can also cause an increase in gas pressure.
It can be dangerous if gas pressure exceeds out pressure, especially if it happens suddenly and without warning. This can lead to explosions or ruptures of containers, which can cause harm to individuals and property. It is important to carefully monitor and control gas pressure to prevent any potential hazards.
Gas pressure can be controlled through a variety of methods. One way is to regulate the temperature of the gas, as increasing the temperature can lead to an increase in pressure. Another way is to limit the amount of gas present in a container, as the number of gas molecules affects the pressure. Using safety devices such as pressure relief valves can also help to prevent gas pressure from exceeding out pressure.
If gas pressure exceeds out pressure in a pressurized system, it can lead to catastrophic failure of the system. This can result in explosions, ruptures, and other hazardous situations. It is important to regularly inspect and maintain pressurized systems to prevent any potential failures due to excessive gas pressure.
