What Is The Density Of Liquid Oxygen? 

Today we will discuss the density of liquid oxygen. Oxygen is common to all of us because we breathe it. Therefore it is also called dephlogisticated air. Oxygen is a highly reactive element in the periodic table, you might have seen various main elements with the suffix ‘oxide’, which means oxygen has reacted with them. When oxygen reacts with hydrogen then one of the most important compounds is formed called water. Oxygen is represented by the chemical formula of O or O2. O is a singular atom of oxygen while O2 is a molecule made of two oxygen molecules. The atmosphere is made of mostly O2, which is what our bodies have evolved to breathe. Let’s know the density of liquid oxygen.  

What Is The Density Of Liquid Oxygen? 

The density of liquid oxygen is 1.141 g/cm3, which is at Standard temperature and pressure. Liquid oxygen is denser than liquid water and is cryogenic with a freezing point of 54.36 K and a boiling point of 90.19 K at 1 bar pressure. The density of liquid oxygen changes with the temperature. When the temperature increases the density decreases while when the temperature decreases the density increases. Let’s have a look at the density of liquid oxygen at different temperatures. Well, the liquid oxygen’s density at 25 0C is 1.141 g/cm3 and it at 50 0C is 1.04 g/cm3. From these two values, you can say that the density of liquid oxygen decreases with an increase in temperature. The liquid oxygen density can be measured in different units such as 

  • The density of liquid oxygen in kg/m3 is 1141 kg/m3 
  • The density liquid of oxygen lb/ft3 is 71.29
  • The density liquid oxygen lb/in3 is 1.141 lb/in3 
  • The density of liquid oxygen lb/gal is 1.141 lb/gal 
  • The density of liquid oxygen in liters is 1.141 kg/L 
  • The density of liquid oxygen per cubic meter is 1141 kg/m3 
  • Energy density of liquid oxygen is .141 g/ml 

Definition Of Density Of Liquid Oxygen 

The definition of the density of liquid oxygen is defined as the ratio of mass to the volume of the liquid oxygen. Or, the amount of liquid oxygen that is compatible with the cubic centimeter space is called the density of liquid oxygen. The liquid oxygen density is directly proportional to the mass and inversely proportional to the volume. This means when you increase its mass, its density also increases, and vice versa. Similarly, when you increase its volume then the density decreases while when you decrease the volume of liquid oxygen then its density decreases. The definition of the density of liquid oxygen can be expressed in the equation form as given below, 

The density of Liquid Oxygen = mass of Liquid Oxygenvolume of Liquid Oxygen g/cm3 

In the symbolic form, 

               D =    mv g/cm3 

Where, d – the Liquid Oxygen density, 

             v – the volume of Liquid Oxygen, and 

            m – the mass of Liquid Oxygen 

How To Calculate Density Of Liquid Oxygen? 

To calculate the density of Liquid Oxygen you need to know some basic formulas and basic procedures. Just follow the procedure as given below, 

  1. Take a small amount of Liquid Oxygen in laboratory equipment. 
  2. The container should have a fixed volume, so you don’t need to determine the volume of Liquid Oxygen. 
  3. Measure the weight of the container filled with Liquid Oxygen and note down the weight. 
  4. Now, deduct the weight of the empty container from the container filled with Liquid Oxygen. 
  5. Finally, divide the mass by volume and you will get the Liquid Oxygen density.

Is Oxygen More Dense As A Solid Or Liquid?

Liquid oxygen, on the other hand, is pure. Also, liquid oxygen is much more dense than gaseous oxygen (as a general rule, the volume of a given sample of gas decreases by a factor of about 800 when it forms a liquid).

What Is The Density Of Liquid Oxygen At STP?

The density of Oxygen is 1.43 g/L at STP.

Is Liquid Oxygen Heavier Than Water?

Liquid oxygen is a weak blue liquid that is somewhat heavier than water. Gaseous oxygen is a colourless, tasteless and odourless gas. Oxygen in itself is not flammable, although it does support combustion. Atmospheric air contains 20,94 vol.

Is Liquid Oxygen Heavier Than Air?

Oxygen, ozone and water vapour are heavier than air, yet none of them sink under gravity. Water vapour forms layers we call clouds, the ozone layer is some 15-30km high and oxygen doesn’t form a layer at all.

Is Liquid Oxygen 100% Oxygen?

LOX delivered in bulk is almost 100% pure oxygen with a dew point lower than −80°C and therefore does not normally require further treatment.


Oxygen is usually liquefied so it can be transported and stored more efficiently in large quantities. However, in most applications, oxygen is used after it has evaporated to a gaseous form. Oxygen’s primary use is because of its powerful oxidizing and life-sustaining properties. Oxygen is commonly used in healthcare and medicine. Steel and steel mills also extensively use oxygen or oxygen-enriched air to effect chemical cleaning and heating associated with carbon removal and other oxidation reactions. Benefits such as fuel and energy savings and reduced total emissions are often achieved by enriching the air or replacing it with cleaner oxygen. This was all about the density of liquid oxygen
