Does double glazing prevent conduction or convection?
Both - Conduction- the gap of air between two panes of glass. Convection - by sucking the air out However, don't say it will be 'prevented' (especially in an exam as you may lose marks!) it is only slowed down,
Where can convection currents form?
Convection currents can form when there a temperature differential within the same body of a liquid or gas and the higher temperature obtains at a lower vertical position than the cooler liquid. If the relative vertical temperatures are reversed, convection currents may be prevented by what is known as a thermocline, i.e., a static layer of liquid which effectively prevents mixing of the different temperatures necessary to produce convection.
When the heated part of the mantle rises through the cooler parts this an example of?
Convection
How is heat loss by convection prevented in a thermal flask?
There is a layer of vacuum which surrounds the flask, then the inside is covered by shiny material which will reflect the heat back into the flask, there are two lids, and there is an indirect gap of about 0.01mm.
Is a convection current the same as a convection?
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
Is a bowl of oatmeal cooling is an example of conduction radiation or convection?
I don’t understand IM ON A TEST LOL (jk it’s convection losers)
What is the scientific name for convection?
The scientific name for convection is "convection."
The transfer of heat by the movement of a fluid?
convection
What is the Difference in normal convection and forced convection?
Forced convection is forced [man-made] and normal convection is natural.
What is a toaster convection or radiation?
convection
Why does convection take place in the atmosphere?
Convection take place because of convection currents
