Ideal Gas Laws

What is Ideal Gas Law?

The Ideal Gas Law is a law which provides the relation among various parameters of the gas such as pressure, temperature, and volume of the gas. According to Ideal Gas Law,

PV = nRT

What is Ideal Gas examples?

There is no such gas which behaves as a perfect noble gas, but we can take some gases which almost behave as Ideal Gas which are, Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, and others.

Who derived the Ideal Gas Law?

Ideal Gas law was first derived by the French physicist Benoît Paul Émile Clapeyron.

Why is Ideal Gas law inaccurate?

Ideal Gas Law is inaccurate because it only works on ideal gas under perfect motion and it fails at a higher pressure and lower temperature.

How is Ideal Gas law used in everyday life?

The ideal gas law is used in everyday life in various scenarios such as,

  • Airbags in the car expand on the basis of the Ideal Gas Law.
  • The coolant gas added in Refrigerators, and AC cools using the principal of Ideal Gas Law
  • The ventilation provided in the high-rise buildings uses the Ideal gas law.

What is the Ideal Gas Equation?

Ideal gas equation is,

PV = nRT

where,
P is Pressure of the Gas
V is Volume of the Gas
T is Temperature of the Gas
n is the number of moles of the gas
R is Universal Gas Constant



Ideal Gas Law

The ideal gas law also called the general gas equation, is an equation that provides the relation among the various parameters of the gas i.e. they provide the relation among pressure(P), temperature(T), and Volume(V) of the gas. It is a combination of Charles’s law, Boyle’s Law, Avogadro’s law, and Gay-Lussac’s law. This law was first stated by the French physicist Benoit Paul Émile Clapeyron in 1834.

What is Ideal Gas?

An ideal gas is a gas that exists only in theory but practically it does not exist. It consists of particles where only elastic collision occurs. An ideal gas is also called a perfect gas.

Absolute Temperature

Thermodynamic temperature is another name for absolute temperature. The value of absolute temperature equals zero Kelvin or -273 °C. The thermodynamic energy of a system is lowest at this temperature. The velocity of the gas particles stops at an absolute zero temperature. This signifies that the particles of the gas really aren’t moving. At absolute zero, the volume of the gas is zero....
