Energy moves from hot to cold
Webtransfer of energy by mass motion of molecules through a fluid Radiation: transfer of energy by electromagnetic radiation through space or air What principle is being demonstrated when hot water goes up and cold water sinks? convection Only the fluid near the ________ source becomes less dense and rises. heat Convection only occurs in ____________. WebIf heat flows from the hotter object into the cooler object (as it will spontaneously), the molecules of the hot object slow down, and the molecules of the cool object speed up, until all the molecules are moving at the same average speed.

WebJust like a hot-air balloon lifting off the ground, blobs or "parcels" of hot air rise from the ground, carrying hot air skyward. This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." A hot air balloon rises because warmer air is less dense than cool air. WebThermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics , deals with how heat is transferred between …
