Energy Transfers and Transformations - National …

WebConduction is defined as the transfer of energy from one atom to another through direct contact – this can either be through ionic conduction, electric conduction, or heat conduction. Conduction can occur in solids, liquids, and gases – solids conduct most efficiently because the molecules are much closer together than in other states, as ... WebConvection is the heat transfer due to the movement of a fluid, such as a gas or liquid, and carries heat energy away from the source of heat. how big is bahrain

Which Of The Following Is Needed For Convection To Happen

WebConvective thermal transfer is due to the displacement of molecules that induces a macroscopic displacement of thermal energy: it occurs in fluids (liquids or gases) and at the interface between a ... WebJan 23, 2024 · Introduction. The principle of thermal convection can basically only occur in materials that have the ability to flow. This applies therefore only to liquids and gases ( fluids ). In solids, however, the molecules are bound to a certain location and therefore cannot flow. Heat transport by convection is therefore not possible in solids. WebConduction. Conduction occurs in solids. Metals are good conductors. Non-metals and gases are usually poor conductors. Poor conductors are called insulators. how many of these images did you highlight
