I Newton's Law of Cooling and Resonance Phenomena

  1. Nov 16, 2016 #1
    Can we find the natural frequency of water's molecules by using of Newton's law of cooling and resonance phenomena?

    Please define "the natural frequency" of a molecule of water.

    Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force. Free vibrations of an elastic body are called natural vibrations and occur at a frequency called the natural frequency.

    Now, assume we want to calculate the natural frequency of a single molecule of water in normal conditions: T = 25 °C and P = 1 atm

    What is the procedure of the solution?

    For starters, it does not make sense to talk about a single molecule at a given temperature and pressure.

    If you are talking about about the vibrational frequencies of a molecule, then you would have to do quantum chemistry calculations or use a simplified mass-and-spring model.

    But I have the feeling that this is not what you are after.
