# Problem: Indicate whether each statement is true or false.CO2(g) and Ar(g) have nearly the same molar mass. At a given temperature, they will have the same number of microstates.

###### FREE Expert Solution

We have to determine whether the given statement is true or false.

To determine if the given statement is true or false, we have to first define what are microstates and the factors on which their values depend upon.

A microstate is a specific way in which the energy of a system can be arranged.

The number of microstates depends upon the molecular motions that take place.

These are:

Translational motion: When molecules move from one point in space to another.

Vibrational motion: When the atoms in a molecule vibrate. This motion results into stretching and compressing of a covalent bond, much like a spring.

Rotational motion: The different orientations of molecules in space.
