Energy Transfer Explained
Radiation is the transfer of energy through electromagnetic waves, with humans emitting mostly in the infrared spectrum, unlike the sun which emits visible light. This leads to thermal expansion, where objects increase in size as temperature rises due to increased molecular movement. Understanding this phenomenon is crucial for engineering, as it explains the necessity of gaps in structures like bridges and railway lines to prevent buckling in hot weather.In this clip
