Liquid oxygen expansion in vaccum

In summary, there are two containers with a 1m x 1m base and different height capacities. One is filled with vacuum and the other with liquid oxygen at a temperature of -190 degrees Celsius. The liquid oxygen has a density of 1140 kg/m3 and can occupy up to half the height of the vacuum container. The objective is to determine the amount of liquid oxygen needed in the vacuum container for an even distribution throughout both the upper and lower half. This must be taken into consideration as the boiling point of liquid oxygen decreases when inside a vacuum container.

Homework Statement



There are 2 containers.Outside temperatue is -190 degree celcius.(boiling point of liquid oxygen is -180 degree celcius).One is filled with vacuum and can have a minimum height of 6000m and other is filled with liquid oxygen (1140 kg/m3 density) at -190 degree celcius which can have a miximum height of half the height of the other container.Both have 1m x 1m base.I want to know how much liquid oxygen should be put in the vacuum container so that when it occupies the entire vacuum container it is distributed nearly equally at both upper and lower half [and not like that it has more mass at the base and very few at the top].[Inside vacuum container it would form gas as its boiling point woul decrease].
Please reply...

Even for a national level competition, you must do your own work. Even if the answer won, I doubt you would share the prize with PF.

Its not that answer to this question will get me a prize but it is a difficulty i am facing theoretically.So i want to clarify it before i start working on this project practically.
 

FAQ: Liquid oxygen expansion in vaccum

What is liquid oxygen expansion in vacuum?

Liquid oxygen expansion in vacuum refers to the process of liquid oxygen transforming into gas when exposed to a vacuum environment. This occurs because the pressure in the vacuum is lower than the pressure of the liquid oxygen, causing it to expand and change states.

How does liquid oxygen expand in vacuum?

Liquid oxygen expands in vacuum through a process called vaporization, where the molecules of the liquid gain enough energy to break free from their liquid state and become a gas. This is due to the lower pressure in the vacuum environment, which allows the molecules to move more freely and escape the liquid.

What are the applications of liquid oxygen expansion in vacuum?

Liquid oxygen expansion in vacuum has many practical applications, including in rocket propulsion systems, medical devices, and industrial processes. It is also used as a coolant in certain scientific experiments and in the production of steel and other metals.

What factors affect the expansion of liquid oxygen in vacuum?

The expansion of liquid oxygen in vacuum is affected by several factors, including the temperature and pressure of the vacuum environment, the initial temperature and pressure of the liquid oxygen, and the volume of the container holding the liquid. The properties of the liquid oxygen itself, such as its density and heat capacity, also play a role.

Are there any safety concerns with liquid oxygen expansion in vacuum?

Yes, there are some safety concerns with liquid oxygen expansion in vacuum. It is important to handle liquid oxygen with caution as it is highly reactive and can cause burns or fires if it comes into contact with certain materials. Additionally, the rapid expansion of liquid oxygen in a vacuum can cause pressure buildup, which may lead to explosions if not properly controlled.
