thermodynamics - How much energy from extreme coldness?



Let's say I have:


1: one mole of extremely cold ideal gas
2: unlimited amount of ideal gas at temperature 300 K
3: one ideal heat engine


Can I generate for example 1 MWh of mechanical energy using those three things?


Alternative formulation: When temperature of the cold gas approaches 0 K, what does the amount of generated energy approach?


(there is no other heat sink than one mole of cold ideal gas)

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 \...
