Key Concepts Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature. Removing energy (cooling) atoms and molecules decreases their motion, ...

The amount of thermal energy also depends on the object's mass and its “specific heat capacity.” That's a measure of how much energy is needed to increase the temperature of the object.

Carbon nanotube-based film achieves record-low thermal conductivity at extreme temperatures, offering ultralight, scalable ...

Hot days tax the body greatly and if your body is not up to the challenge, excessive environmental heat can result in severe injury and even death.

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory also found low-temperature thermal energy networks to be more efficient than high temperature systems in a ...

Op-ed: Despite federal setbacks on clean energy, local ownership of TENs is allowing cities and towns to meet their climate ...
