Convection refers to a movement caused within a fluid by the tendency of hotter material to rise and colder or denser material to sink under the influence of gravity. Four examples of convection are the following: boiling water, steaming cup of hot tea, melting ice and thawing frozen material.
If you have 'radiators' heated by hot water, these give up most of their heat to the room by convection, that is currents of air are set up by the thermal gradients which continually cause warm air to rise and cooler air to fall, so the heat circulates. Actual radiant heat is not so effective at the temperature of the hot water, so to call the units 'radiators' is not correct, but it has become ingrained as a habit to do so
5 examples of convection in science...viz
water heated in a kettle,
tidal waves formation,
cooling of electronic equipments,
fluid radiator system in vehicles,
colling of nuclear reactor under normal conditions
There are several things that are examples of convection. A few are hair dryers, fans, ocean currents, conventional ovens, and cooling fans in computers.

no an example of a convection current is a blow drier
The heating alone is not, no, but the convection it sets up, thus forming winds and weather systems, is a valid example.

An example convection is write down your notes in class so you know what it is.

yes a hard boiled egg is an example of convection!!!
I learned what convection means in science class.
Hot Air Rising And Cooler Air Falling Is One Example Of Convection Which That Example Is Called Convection Currents. Example Two An old-fashioned radiator creates a convection cell in a room by emitting warm air at the top and drawing in cool air at the bottom.

I donβt understand IM ON A TEST LOL (jk itβs convection losers)
