What is a Real Gas.

Example of real gas. 1 mole of He weighs 4 g and would occupy 4 01785 dm 3 224 dm 3. That means that 01785 g of helium occupies 1 dm 3 at stp. Because LNG occupies only about 1600 the volume of natural gas.

Nitrogen oxygen carbon dioxide carbon monoxide helium etc. An ideal gas is a gas at low pressure and fairly high temperature in which the individual gas atoms or molecules can be assumed to be far apart and to not interact with each other. Real gases have small attractive and repulsive forces between particles and ideal gases do not.

It is prepared by cooling natural gas to below about 162C. Boyles law relates the pressure of a gas to its volume. A gas particle has a definite volume and mass.

Now we solve some problems related to ideal gas law for better understanding follow each example carefully. Gas Ideal Gas Gas Laws Intermolecular Forces Real Gas. C 1 0874 C 2 0083 C 3 0022 i-C 4 0006 n-C 4 0002 i-C 5 0008 n-C 5 0003 n-C 6 0001 and C 7 0001.

Any gas that exists is a real gas. One important real life use of the Ideal Gas Law is in engineering. The law was discovered by Robert Boyle in the seventeenth century.

Nitrogen Oxygen Carbon dioxide are common examples of real gas. Find pressure of 88 g CO 2 at 27 0 C in container having volume 1230 cm 3. He found the pressure of a gas is inversely proportional to its volume at a constant temperature for a fixed amount of the gas.
