Question

Define degrees of freedom of a gas molecule
How many degrees does a monoatomic gas
have ​

Answer 1

three degrees

Explanation:

So, the translational motion of the molecule of a gas has three degrees of freedom associated with it. This is irrespective of the atomicity of the molecule. This means that whether it is a monoatomic, diatomic, triatomic or polyatomic molecule; it will have three translational degrees of freedom.

Answer 2

Answer:

The largest number of logically independent values that is, values with the freedom to change in the gas are referred to as the degrees of freedom. A monoatomic gas has ​three degrees of freedom.

Explanation:

• A molecule's degree of freedom is how many different ways it can move, rotate, or vibrate in space when it is in the gas phase.
• It can be defined as the largest number of logically independent values—that is, values with the freedom to change in the gas are referred to as the degrees of freedom.
• Translational, rotational, and vibrational degrees of freedom are the three different types.
• The number of atoms in a molecule and the geometry—the arrangement of the atoms in space—of the molecule both affect the number of degrees of freedom of each kind the molecule possesses.
• The ability of a molecule to store and disperse its energy is fundamentally described by these molecular degrees of freedom.
• The system's degrees of freedom are determined by,
• f = 3 N - K where N is the number of particles in the system and f is the degrees of freedom. K is the independent relationship between the particles.
• When N = 1 and K = 0, a monatomic gas has f = 3 x 1 - 0 = 3.
• In terms of the degree of freedom, a monoatomic gas has three.

Thus, the largest number of logically independent values that is, values with the freedom to change in the gas are referred to as the degrees of freedom and a monoatomic gas has ​three degrees of freedom.
