The models of specific heat based on equipartition of energy and including rotational degrees of freedom as well as translational are able to explain specific heats for diatomic molecules. The departure from this model in the case of polyatomic molecules indicates vibrational involvement

Whether and climate Weather is the condition of the atmosphere in terms of temperature, humidity, winds and precipitation Climate is defined as the average weather over various time periods ranging from a few weeks to decades to geological timescales Whether and climate are ultimately determined by location, topography, and the exchange of radiant energy between the Sun, Earth, and space
