Did you know?
WebAs air is heated, the particles gain heat energy allowing them to move faster and further apart, carrying the heat energy with them. Warm air is less dense than cold air and will rise. Cooler air moves in below to … WebAlso to extract (heat) energy, would mean to move it from a higher temperature to lower temperature (potential), just like any other form of energy, whether electricity or fluid dynamics. In your case of "5104 kJ of energy", 100% of it could be extracted for work if the environment was at absolute zero and your extractor efficiency was at 100%.
