I would say the answer is D
Paint samples received by forensic laboratories are usually in the form of small chips or smears. Infrared (IR) spectroscopy is one of the most commonly used tools available for the analysis of these types of samples and serves as a staple comparative technique in the assessment of whether or not a questioned sample could have come from a suspected object
The most direct way to probe the vibrational frequencies of a molecule is through infrared spectroscopy. This is because vibrational transitions typically require an amount of energy that corresponds to the infrared region of the spectrum. Raman spectroscopy, which typically uses visible light, can also be used to directly measure vibration frequencies.
The explanation for the large space between particles in a gas is provided by the kinetic theory (option C).
<h3>What is the kinetic theory?</h3>
The kinetic theory is a scientific theory used in physics to understand the behavior of gases.
This theory (kinetic theory) indicates that molecular distances in gases are small when compared to the molecular sizes.
In conclusion, the explanation for the large space between particles in a gas is provided by the kinetic theory (option C).
