Question

can any one explain The Ideal Gas Equation and its derivation?
Plz Explain Fast Its urgent.........

Answer 1

The ideal gas equation helps us to co-relate values of pressure, temperature, volume and number of moles. ... According to the Charles' Law, at constant pressure, the volume of a fixed mass of a gas is directly proportional to its absolute temperature.

Answer 2

$\huge\textbf{Ideal Gas Equation :}$

A gas that follows Boyles law, Charles law, Avogadro law is called an Ideal gas law. 

At constant T and n, 

V is inversally proportional to P [Boyles law] ...(1)

At constant P and n,

V is directly proportional to T [Charles law] ...(2)

At constant P and T,

V is directly proportional to n [Avogadro law] ...(3)

By combination of equation (1), (2) and (3) we get;

$V$ $\alpha$ $\frac{nR}{T}$

$V\:=\:R$ $\frac{nT}{P}$

$\textbf{PV = nRT}$

(Ideal Gas Equation)

In this;

P = Pressure of gas

V = Volume of gas
