Consider a gas of O2 molecules (weight 32 g/mol). The temperature of the gas is such that rotational and translational degrees of freedom are active. When the rotational energy is increased by 5.90e-21 J per molecule by adding heat, by how much is the typical translational energy per molecule increased

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
