"WebAs the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth. The faster this air moves, the cooler you feel. Radiation occurs when heat radiates across the space between you and the objects in your home. If objects are warmer than you are, heat will travel toward you. " - How fast does heat travel

Web5 nov. 2014 · 2,648. Heat travels in three ways: Conduction, convection, and radiation. Conduction is when objects of different temp come into contact, and the vibrating molecules from the hotter object increase the vibration of the molecules in the cooler object, thereby cooling the hotter object and heating the cooler one. WebSolution. Heat transfer takes place from the body at a higher temperature to a body at a lower temperature. We know that infrared waves are also called heat waves. Heat radiations use electromagnetic waves to transfer heat from one body to another body. The speed of an electromagnetic wave is 3 x 10 8 m/s.
