Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body ...

Driving force An experiment has confirmed that an oscillating temperature gradient boosts heat flow in fluids. (Courtesy: iStock/Mervana) Physicists in the Czech Republic have shown that heat flows ...

Keeping electronic devices cool is important when considering both their function and durability, as temperature influences material properties and energy flow. The temperature of "hot spots" that can ...

Thermodynamics, as with most concepts in science and physics, is most accurately described using mathematical equations. However, simple explanations, although not perfectly accurate, are sufficient ...

Recent models for the chemical composition of the continental crust rely on various geophysical, geological, and petrological constraints and display a wide range in ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes.

The strange world of quantum mechanics just got a little stranger with the discovery that a magnetic field can control the flow of heat from one body to another. First predicted nearly 50 years ago, ...

This redirected heat flow boosted the PTE effect by aligning temperature changes with variations in how the material responds to heat—essentially enhancing current production. Discover the latest in ...
