Internal Energy OF Molecules

Thermodynamics - Internal Energy Of Mixture Of Gases

Regarding the internal energy of the molecule, which of the following statement is correct?

Translational Kinetic Energy Of Gas Molecule |Degree Of Freedom|Internal Energy

Calculate the internal energy of one mole of a diatomic gas at 300 K. Assume the molecules to be rigid.

From the conditions of the foregoing problem find : (a) the number of molecules whose potential energy lies within the internal from U to U + dU , (b) the most probable value of the potential energy of a molecule , compare this value with the potential energy of a molecule located at its most probable distance from the centre of the field.

Statement-1: In kinetic theory of gases, we do not take into account the change in gravitational potential energy of the molecules. Statement-2: The internal energy of a gas depends on the interaction between gas molecules. This interaction is not affected by the change in gravitational potential energy of the molecules.

Internal energy is sum of

Assertion : Internal energy is an extensive property. Reason : Internal energy depends upon the amount of the system.
