Web22 dec. 2014 · Now I wonder why heat is lost as it travels slightly. My first hypothesis is that as light/heat (radiation) travels, the light loses its energy through interactions with particles and air molecules, gives them energy and therefore loses its energy. This may be a valid (or credible) hypothesis locally (on Earth), however, in space, this loses ... Web30 sep. 2016 · September 30, 2016 at 6:15 am. Throughout the universe, it’s natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. WebRadiation heat transfer ability be described by reference till one 'black body'. This Black Body.
