# What Is The Density Of Liquid Nitrogen?

Today we will see the density of liquid nitrogen. But before that, understand liquid nitrogen. You might have seen an interesting cloud-like structure of fog when a waiter opens a dish of food to serve you in top restaurants, this is nothing but liquid nitrogen. It has also become increasingly common at top restaurants as a method for instantly freezing food and drinks. It has a large expansion rate of evaporation, and one litre of liquid nitrogen can result in about 700 litres of gas. If it is added to a liquid such as an ice-cream mixture, it cools at the table, the rapid freezing produces an ice cream with particularly small ice crystals which has a very smooth texture. Let’s know the density of liquid nitrogen

## What Is The Density Of Liquid Nitrogen?

The density of liquid nitrogen is 0.807 g/mL, which is measured when pure nitrogen is in its liquid state at 320 F and 1 ATM of pressure. Liquid nitrogen density can vary with the pressure. Let’s know the density of nitrogen at different pressures. The density of liquid nitrogen at 0.013 MPa is 867.2 g/L while it at 0.033 is 842.8 g/l. From this, you can conclude that the density of liquid nitrogen is inversely proportional to the pressure. When pressure increases the density decreases and vice versa.

Here are different values of the density of liquid nitrogen at different units,

• The density of liquid nitrogen kg m3 is 900 kg/m3
• The density of liquid nitrogen liters is 0.807 gm/l3
• The density of liquid nitrogen km/m3 is 806.4 km/m3
• The density of liquid nitrogen g/cm3 is 0.8064 g/ml
• The density of liquid nitrogen at STP is 0.807 g/mL
• The density of liquid nitrogen kg/l is 807 kg/l3
• The nitrogen density g/ml is 0.807 g/ml
• The density of nitrogen per liter is 0.807 gm/l3

Now, you know that the liquid nitrogen has a density of 0.808 g/ml. Let’s know the definition of the density of liquid nitrogen.

## Definition Of Density Of Liquid Nitrogen

The density of liquid nitrogen is defined as the ratio of mass to the volume of liquid nitrogen. The thermal effects remarkably influenced the liquid densities of liquid nitrogen. Therefore, consider the compressibility of cryogenic cavitating flow on the basis of thermal effects if necessary while calculating the density of liquid nitrogen. Let’s know the density of liquid nitrogen definition in the equation form as,

The density of Liquid Nitrogen = mass of Liquid Nitrogenvolume of Liquid Nitrogen g/cm3

In the symbolic form,

D =    mv g/cm3

Where, d – the Liquid Nitrogen density,

v – the volume of Liquid Nitrogen, and

m – the mass of Liquid Nitrogen

Now, you know the formula to know the liquid nitrogen density. Let’s learn how to calculate density of liquid nitrogen.

## How To Calculate Density Of Liquid Nitrogen?

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

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

Let’s consider an example,

What is the density of liquid nitrogen at room temperature and standard pressure?

You know, room temperature is 250  c and liquid nitrogen’s mass is 807 g and volume is 1000 ml.

By using the formula,

The density of Liquid Nitrogen = mass of Liquid Nitrogenvolume of Liquid Nitrogen

= 807/1000

= 0.807 g/ml

## FAQ

### Is Liquid Nitrogen Less Dense Than Water?

Because the liquid nitrogen is less dense than the water, it just floats on top instead of mixing in. And while it does, it sometimes forms a tiny bit of ice beneath it, which acts as an insulator and keeps the warm liquid somewhat separate from the cold nitrogen.

### Is Liquid Nitrogen Heavier Than Air?

Nitrogen gas is only slightly lighter than air and readily mixes with air at room temperature. Cold vapors are more dense and will settle.

### How Many Pounds Is A Gallon Of Liquid Nitrogen?

32% of the weight is nitrogen – hence the “32.” This roughly equals 3.4 pounds of nitrogen per gallon, or 55 ounces

### Can You Touch Liquid Nitrogen?

Liquid nitrogen has a boiling temperature of -196°C at atmospheric pressure. Direct contact can freeze the skin causing frostbite and cold burns. Delicate tissue, such as eyes, can be damaged by an exposure to the cold gas alone which would be too brief to affect skin.

### What Is The Density Of Liquid Nitrogen At STP?

approximately 1.25 g/L

Answer and Explanation: The density is approximately 1.25 g/L.

### What Is The Density Of Nitrogen In Lb Ft 3?

0.07807 lb/cubic foot

At 32 degrees Fahrenheit and one atmosphere of pressure, nitrogen gas has a density of 0.07807 lb/cubic foot (0.0012506 grams/cubic centimeter).

### Is Dry Ice Liquid Nitrogen?

Often confused with its chilly cousin, liquid nitrogen, dry ice is actually just cooled and condensed carbon dioxide. It skips the melting process and sublimates directly into carbon dioxide gas when it reaches room temperature and pressure. Dry ice is extremely cold, and hovers around -109.3 degrees Fahrenheit.

## Conclusion

Liquid nitrogen is the liquefied form of the element nitrogen and it is produced commercially by the fractional distillation of liquid air. Liquid nitrogen is denoted as LN2, LN, or LIN. liquid nitrogen is cold enough to cause severe frostbite in contact with living tissue. So, you wear proper safety gear when handling liquid nitrogen to prevent its contact or inhalation of the extremely cold vapor. It is commonly used as a coolant for superconductors, vacuum pumps, and other animal genetic samples. It is also used in cryotherapy to remove skin abnormalities and as a shielding material from oxygen exposure. This was all about the density of liquid nitrogen
