Identify three situations in which convection occurs
hodyreva [135]

There are three types of heat conduction through substances. These are named as conduction,convection and radiation .here we have been given convection.

Convection is the type of mode of conduction of heat in which heat will flow though a liquid and gases due to the direct physical movement of particles.In this process the hotter particles will go upward as they become lighter and cooler,heavier particles come downward which after being heated up go upward .Hence a convectional current is formed for which whole of the liquid or gas gets heated.

There are different life examples of convection.

One may take an simple example of water in a container.The water molecules which are present bottom part of the container  will be heated up first and go upward.The upper particles will come downward and they will constitute a convectional current.

Another life example is the flow of wind from one region to another region.the air at hotter region will become lighter and goes upward and the wind starts flowing from cold region region  in order to occupy the vacant space.

Another example is the hot air balloon rising up..It is also another example of convection of heat
