The principle of entropy is known to apply to all classical ... transformations can be made reversible, just like work and ...

Our intuitions about entropy mostly come from experience with ... come to recognize that gravitating systems can have a negative heat capacity and so increase their temperature on the emission ...

Quantum systems may defy classical time irreversibility, revealing bidirectional entropy flow and prompting a reevaluation of ...

a hot object transfers heat to its cold surroundings because the heat transfer leads to an increase in the total entropy,” said Rijal. “But we found for organic molecules arranged in a ...

The development of high-performance joints for high-entropy carbides (HECs) represents a critical advancement for applications in extreme ...

The cooling effect means that it is an endothermic process (D H>0) so that TD S is positive. Thus the entropy of the rubber band increases when it goes from the stretched state to the natural state.

The intersection of quantum theory and thermodynamics has long intrigued and puzzled researchers. The Second Law of Thermodynamics, which states that the entropy of an isolated ... Continue Reading → ...
