Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as ...

Thermodynamics adds a new quantity, called internal energy, into the fold; it’s the energy possessed by the system itself. Getty Images If we add heat to the system, its internal energy increases.

The Second Law of Thermodynamics says, in simple terms, entropy always increases. This principle explains, for example, why you can't unscramble an egg.

The scientific study of obesity has been dominated throughout the twentieth century by the concept of energy balance. This conceptual approach, based on fundamental thermodynamic principles ...

Can energy move from a colder to a hotter region in a material without violating the second law of thermodynamics? Yes, according to physicists from Trinity College Dublin and the Universidad ...

The first law of thermodynamics states that energy can neither be created nor destroyed, but it can be converted into different forms. "Suppose you heat up a balloon," Cassak said.

Nanoscale thermodynamics plays a crucial role in the development of advanced materials and devices for energy harvesting and conversion. Thermoelectric materials, which convert temperature gradients ...
