Convection works best in fluids like air and water, where temperature differences lead to density variations and create fluid motion. It is commonly seen in the Earth's atmosphere, oceans, and in heating systems like radiators and hot air balloons.
A pot of boiling water is a good analogy for convection. As the water at the bottom heats up, it becomes less dense and rises to the top. Cooler water then replaces it at the bottom, creating a continuous circulation pattern. This is similar to how convection currents work in fluids and gases.
No, voltaic cells (most of what you call "batteries" are actually voltaic cells) work by oxidation and reduction. "Isothermal convection" is a term with which I am unfamiliar that seems like an oxymoron; if everything is the same temperature (isothermal) then convection won't occur, because temperature differences are what drive convection.
I don't think such a thing as a "best" example exists. Here are some examples; take your pick which of these you like "best"; or look for additional examples:* In part of the Sun, energy is transported outwards through convection. * When you boil water (or, for that matter, anything that contains water), convection will make the water move around in the pot. * In solar panels - of the type that heat water - convection moves colder water from the tank to the panels, and it moves hotter water back to the tank. * Wind is the result of convection.
Convection is the transfer of heat through the movement of fluids, such as air or water. In everyday life, convection can be seen in actions like boiling water, where heat causes the water at the bottom of the pot to rise and circulate, creating a convection current. Other examples include the circulation of warm air in a room due to a heater, or the movement of hot air rising from a radiator.
The scientist who first proposed thermal convection was Henri Bénard, a French physicist, in 1900. Bénard conducted experiments with heated fluid in a shallow circular dish, observing the formation of convection cells as a result of temperature differences. His work laid the foundation for the study of convection in fluid dynamics.
no it does not.

Convection ovens have a fan in them which circulates the air. That makes for faster cooking (20%)

Heat energy and a temperature difference.
Convection occurs best in fluids, such as air or liquids like water. This is because fluids are easily able to move and transfer heat through the process of convection. Solid materials do not readily allow for the movement of particles, so convection is less efficient in solids.

Yes, titanium cookware works well with convection heat. Titanium is a good heat conductor, allowing it to heat evenly in convection ovens. Just be sure to follow the manufacturer's guidelines for safe use in convection settings.
Currently, the best Convection Microwave Oven on the Market as of 2013 is the Whirlpool WMH3205XVS 2.0. This model is Stainless Steel and has 1000 Watts of power.

Convection microwaves work by using a fan to circulate hot air around the food, which helps to cook it more evenly and efficiently. This combination of microwave and convection cooking speeds up the cooking process and ensures that the food is cooked thoroughly.
