At the bottom of a substance, part of it is heated by something. This causes it to rise above the rest. However, it soon cools and drops back down again where it is then heated, etcetera. This forms a constant current of part of the substance rising then dropping and repeating.

What are the roles of density and temperature in convection?
Density and temperature play key roles in convection. As air or liquid is heated, its density decreases, causing it to rise. Cooler, denser air or liquid then moves in to take its place, creating a convection current. This cycle allows for the transfer of heat through the movement of the fluid.
Is convection current kinetic energy before transferring?
In a convection current the kinetic energy will most likely be a small part of the total as the rate of flow won't be very high. Most heat transfer in convection will be simply thermal energy transfer, ie from a warmer place to a cooler one.
How does convection take place in your boiler?
In a boiler, convection occurs when heated water or steam rises naturally due to its lower density, creating a convection current. This helps to transfer heat from the combustion gases to the circulating water or steam. The heated water or steam then moves towards the radiators or other heat transfer surfaces, releasing heat and cooling down to create a continuous cycle of convection.
When an electric current is passed in an electrolytic cell how can we make out that electrolysis is taking place?
Electrolysis in an electrolytic cell can be identified by observing the production of gas bubbles at the electrodes, indicating a chemical reaction is occurring. Additionally, changes in the color of the electrolyte solution or the deposition of solid material on the electrodes can also signal electrolysis. A measurable change in voltage or current can further confirm that the process is taking place.

Why can convection of current not take place when solids are heated?
Convection requires the movement of a fluid medium to transfer heat. Since solids do not have the ability to flow like liquids or gases, convection of current cannot take place in solids when they are heated. Heat can still be transferred through conduction in solids, where it is transferred from one molecule to another through direct contact.
What are the two layers of earth in which convection current takes place?
Mantle is one, and I'm gonna guess core.
Difference between conduction current and displacement current?
Conduction refers to electrons or, "holes" in the case of semiconductors, which are conducted, under the influence of an electric field, from one place to another. However, in semiconductor there is a phenomenon called "drift current" which is more a function of very small field and random motion from one place, within the material, to another place. But neither of these is ever referred to as a "convection" current. The term "convection" is used in connection with air currents moved by differences in temperature between one place and another. Hot air tends to rise while cold air tends to fall. Consequently, a circulation of air, due to temperature is called a convection current.
What are the Examples Between Conduction And Convection?
An example of conduction is when a metal spoon in a hot drink gets hot at the handle end. An example of convection is when warmer air rises, causing cooler air to move in and take its place, creating a convection current.
Is war still happening today?
