A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the ...

By using the right materials, you can get an object to radiate more energy than it absorbs, dropping its temperature by a few degrees. It seems too good to be true, but it works, thanks to some ...

The kinetic energy of an object is the energy it has because of its ... For example, kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a ...

All materials radiate thermal energy based on their temperature. The hotter an object, the more it will radiate. The sun is a clear example of heat radiation that transfers heat across the solar ...

Energy can transfer by heating from a hotter region to a cooler region. Find out more with BBC Bitesize. For students between the ages of 11 and 14.
