Question

what do you mean by degree of freedom? find degree of freedom of diatomic gas

Answer 1

The total number of independent modes(ways) in which a system can possess energy is called Degree of freedom.

Diatomic gas- A molecule of diatomic gas has five degrees of freedom (3 tanslational and 2 rotational).

Answer 2

Degree of freedom

Thhe number of independent ways in which a molecule or an atom can exhibit motion or have energy is called its degree of freedom.

Else in simple terms "The number of independent coordinates required for a system is called a degree of freedom..."

It is denoted by "f"..

Types of degree of freedom :

• Translational degree of freedom.
• Rotational degree of freedom.
• vibrational degree of freedom.

For diamtomic Gases :

diatomic gases include O2, cl2 , N2 etc.

So by taking each type of degrees into account let's calculate,

1. Transitional : 3
2. Rotational : 2

So totally Degree of freedom will be :

2+3 = 5

Hence degree of freedom for a diamtomic Gas is 5 at low temperature.
