How Do Multiple Gases Affect Pressure When Compressed into a Liquid?

In summary, the air we breathe is primarily made up of nitrogen and oxygen, with small traces of other chemicals. If we were to compress this air in a container, the pressure would eventually stop increasing as the gas turns into a liquid. However, none of the chemicals in the air can be condensed at 20 degrees Celsius due to being above their critical pressures.

As we all know, the air we breath is made up of appox... 78% Nitrogen ... 21% Oxygen ... and then traces of other random things.

Lets consider that only the oxygen and nitrogen exist so that we neglect the other chemical traces.

If I were to fire up a compressor that pumps outside air into a container. we raise the pressure of the container until eventually the pressure stops to increase because the gas starts to form a liquid. But how does there being two chemicals effect the pressure of the tank. does one of the chemicals start to become a liquid but the vapor pressure of the tank continue to rise until the next chemical can become a liquid?

Out of all of the chemicals considered to be in the air (Nitrogen, Oxygen, Neon, Argon, CO2...etc.) What will become a liquid first at 20 degrees celcius?

None of them. They are all above their critical pressures and can't be condensed at 20 C no matter how much pressure is applied.
 

1. What are the laws of temperature and pressure?

The laws of temperature and pressure are fundamental principles in physics that describe how the temperature and pressure of a gas are related. These laws, known as Boyle's law, Charles's law, and Gay-Lussac's law, explain the behavior of gases under different conditions.

2. What is Boyle's law?

Boyle's law states that the volume of a gas is inversely proportional to its pressure, assuming that the temperature remains constant. This means that as the pressure of a gas increases, its volume decreases, and vice versa.

3. How does Charles's law relate to temperature and pressure?

Charles's law states that, at a constant pressure, the volume of a gas is directly proportional to its temperature. This means that as the temperature of a gas increases, its volume also increases, and vice versa.

4. What is Gay-Lussac's law?

Gay-Lussac's law states that, at a constant volume, the pressure of a gas is directly proportional to its temperature. This means that as the temperature of a gas increases, its pressure also increases, and vice versa.

5. How are the laws of temperature and pressure used in real-world applications?

The laws of temperature and pressure have many practical applications, such as in the design of gas-powered engines, refrigeration systems, and weather forecasting. These laws also help scientists understand and predict the behavior of gases in various environments.
