thermodynamics - Relationship between degrees of freedom and heat capacity and absolute zero?


The Wikipedia article on heat capacity indicates that there is a relationship between the number of degrees of freedom and the heat capacity. I understand this in terms of the equipartition theorem but how I can't understand how this can be used to explain that heat capacity must go to zero as absolute temperature goes to zero (since here equipartition theorem will not hold). So please can someone intuitively explain this to me?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
