Mountain permafrost is warming and thawing worldwide due to climate change, with ground temperature being a key control of ...

For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to ...

In some cases, heat conduction can even be dramatically limited by the fact that different isotopes of an element are built into the material -- i.e. similar atoms with different numbers of neutrons.

When room-temperature washers are placed in hot water, the temperature of the washers increases and the temperature of the water decreases. Energy from the water is transferred to the washers. When ...
