Question

What is an ideal gas and real gas derive the ideal gas equation?

Answer 1

Answer:

The properties of an ideal gas are:

An ideal gas consists of a large number of identical molecules.

The volume occupied by the molecules themselves is negligible compared to the volume occupied by the gas.

The molecules obey Newton's laws of motion, and they move in random motion.

The molecules experience forces only during collisions; any collisions are completely elastic, and take a negligible amount of time.

Answer 2

Explanation:

There are several ways to derive the Ideal Gas Law, but the simplest way is to use the three simple gas laws.

AVOGADRO'S LAW states the volume of a gas is directly proportional to the number of moles.

V ∝ n

BOYLE'S LAW states that the volume of a gas is inversely proportional to its pressure.

V ∝ 1/P

CHARLES'S LAW states that the volume of a gas is directly proportional to its Kelvin temperature.

V ∝ T

If we combine these laws, we get

V ∝ nT/P

We covert the proportionality to an equality

V = knT/P

We replace k with the universal gas constant R and get

V = nRT/P

This can be rearranged to give the IDEAL GAS LAW

PV = nRT
