Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.

trust me i had this in my usatestprep, also follow me on tiktok, its ultrasolos
The 5 rotational levels would there be between the ground vibrational state and the first excited vibrational state.
What is rotational levels?
The three major moments of inertia IA, IB, and IC determine the rotational energy levels for a nonlinear molecule. They revolve around three axes that are mutually orthogonal to one another and have their origin (or intersection) at the molecule's Centre of mass.
What is vibrational state?
The rotation of the molecule brought on by various vibrations in perpendicular planes is described by (123) or (12l23), where 0 l2 2 is an angular momentum quantum number.
Therefore , 5 rotational levels would there be between the ground vibrational state and the first excited vibrational state.
