WebConvection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. An example of convection current is shown in Fig. 7.16. Inside a beaker, hot water rises at the point where heat is applied. The hot water moves to the surface, then spreads out and cools. Cooler water sinks to the ... WebHot regions of a fluid or gas are less dense than cooler regions, so they tend to rise. As the warmer fluids rise, they are replaced by cooler fluid or gases from above. In the example …

WebConvection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid. Convection is the process of heat transfer in fluids by the actual ... WebJun 6, 2015 · The heat loss curve for cup A should be steeper than the curve for cup B. As you can see, the greater temperature difference ($∆T$) results in a greater rate of heat transfer from the cup to the ambient space. Convection also plays a part in heat transfer. Convection is the movement of fluid inside the cup that circulates heat throughout the cup.

WebHow does heat flow through convection? When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises. …. A space heater is a classic convection example. WebConvection is driven by buoyancy—hot air rises because it is less dense than the surrounding air. Sometimes, we control the temperature of our homes or ourselves by …
