## What is an ideal gas?

Many unsystematically moving particles that interact with each other by mean of elastic collision and follows a specific law, an elementary equation, and is responsive to examination known as an ideal gas. In general, a gas can act asideal if the temperature is high and pressure is low as under such condition potential energy becomes less significant as compared to the kinetic energy. According to the IUPAC, a single mole of an ideal gas displays a capacity of 22.710947(13) liters under the standard temperature and pressure conditions.

### Equation:

It follows an elementary calculation that is recognized as the ideal gas law equation: PV = nRT

• n = it represents the number of substances
• R = it is known ideal gas constant and universally accepted = 8.3145 J/mol K
• T = standard temperature
• P = standard pressure
• V = it signifies volume

This tool follows the ideal gas equation, therefore, it is also known as PV = NRT calculator.

### Laws:

Furthermore, there are certain rules known as ideal gas laws. They are:

•  Particles of the Ideal gas have no attraction or resistance for each other.
•  The communication between ideal gas particles would be an elastic collision.
•  On interaction with the walls of the container,all the particles will bounce back i.e. elastic collision.
•  Boyle’s Law: It states that if temperature and gas quantity remains unchanged then the pressure will be multiplied by its volume and remains constant. (p1. V1 = p2. V2)
•  Charles’s Law: states that if we keep the pressure and gas quantity constant and dived by its temperature then it will be constant as well. (V1 / T1 = V2 / T2)
•  Gay-Lussac’s Law: For a constant volume and quantity the pressure divided by its temperature is constant. (p1 / T1 = p2 / T2)
•  Avogadro’s Law: It states that if the temperature and pressure are constant and we divide the gas volume by its quantity then it will come out as a constant as well. (V1 / n1 = V2 / n2)
•  Combined Gas Law: it states that if the quantity of gas is constant and pressure multiplied by volume and divided by the temperature then the outcome will be constant as well. (p1. V1 / T1 = p2. V2 / T2)

At very low temperatures and higher pressure, the ideal gas model fails as intermolecular forces and molecular size turn out to be more significant. It also flops for heavyweight gases; such as observe in many refrigerants.

## How to calculate ideal gas law?

For the calculation of ideal gas law, it is necessary to follow the equation for precise output.

Ideal Gas Equation: PV = nRT

To calculate ideal gas law:

To calculate the ideal gas law, you have to use above mentioned ideal gas formula to put the given values in it. Now the manual calculation is a tricky thing to do and involve mathematics. To avoid the problem this ideal gas law calculator is all there to help you out. Furthermore, the temperature is “absolute” in the equation: Kelvin.Let’s elaborate it with example:

### Ideal Gas Law Example:

Calculation by ideal gas formula:

Case 1: If you are asked to find the volume from the 0.250 moles gas at 200kpa and 300K temperature = 200 kPa, n = 0.250 mol, T = 300K, R = 8.314 J K-1 mol-1?

• You have to put all the values in equation: Volume(V) = nRT / P = (0.250 x 8.314 x 300) / 200 = 623.55 / 200 Volume(V) = 3.12 L This example will guide you to calculate the volume manually.

Case 2: If you are asked to calculate the temperature from the 250ml cylinder containing 0.50 moles gas at 153kpa.V = 250ml -> 250 / 1000 = 0.250 L, n = 0.50 mol, P = 153 kPa, R = 8.314 J K-1 mol-1?

• Put the provided values in the temperature equation: Temperature(T) = PV / nR = (153 x 0.250) / (0.50 x 8.314) = 38.25 / 4.16 Temperature(T) = 9.2 K. Other than this you can use ideal gas law calculator for the final results.

## FAQ’s:

### What does the ideal gas law calculator?

The tool that is specialized for finding an unknown value in the ideal gas law which states PV=nrt. P=pressure, V=volume, n=number of moles of gas, R=the gas constant, and T=temperature. In simple words, this calculator use smart ideal gas law formula to perform ideal law gas calculation.

### How do you find volume using ideal gas law?

To find out the particular volume of any gas, some essential information is required such as: If the amount of gas is in moles, simply a multiplication of it by 22.4 Liters/mole will provide you the result. For illustration, if 2 moles of N2 gas is present, the gas takes up 44.8 Liters.

### What is an ideal gas vs Real gas?

Ideal gases won’t have any attractive or repulsive forces between their molecules but real gases have. Furthermore, Real gas always has some volume but ideal gases do not. lastly, Real gas particles collide and lose their energy but in the case of an ideal gas, collision is perfectly elastic.

### Can you use ATM in PV nRT?

It is a unit. Have a look at the formula to observe the correct units:P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•KT = Temperature (Kelvin). Accurate units are important. Be sure to change whatsoever units you initiate the calculations into the suitable units when using the ideal gas law.

### Why is it called ideal gas law?

It is the condition in which gas shows a particular, perfect relation between its pressure, volume, and temperature so it is considered as ideal gas law. A will not follow the equation when situations are near the condensation point.

### What are examples of ideal gases?

In most normal circumstances such as at standard temperature and pressure, almost each real gases act just like an ideal gas. For some gases such as nitrogen, oxygen, hydrogen, and some heavier gases like carbon dioxide it is possible to treat them like an ideal gas with rational acceptances.

### What is specific volume formula?

Specific volume can be calculated: equals volume/mass. Mostly volume is measured and expressed in cubic meters (m3), and mass is expressed in kilograms. Specific volume is then computed by simply dividing. As a result, you will have a specific volume.

## Takeaway:
