Web9 feb. 2024 · Heat is initially transferred from the Bunsen flame through the glass wall of the beaker by conduction. The water in the region of the Bunsen flame is heated. It expands, becomes less dense and rises. Convection can be "forced" by movement of a fluid by means other than buoyancy forces (for example, a water pump in an automobile engine). Thermal expansion of fluids may also force convection. In other cases, natural buoyancy forces alone are entirely responsible for fluid motion when the fluid is heated, and this process is called "natural convection". An example is the draft in a chimney or around any fire. In natural convection, an increase in temperature produces a redu… litexshop.comWeb25 mrt. 2024 · Convection involves movement of a heated fluid, such as air, usually a fairly rapid process.
