Question

define convection what are the other words of heat transfer​

Answer 1

convection is transfer of heat from one position to another with motion of molecules

it is only possible in liquids and gases as in these two states only atoms or molecules are somewhat free to move.

ye uniform process hai yrr and gravity is compulsary for natural convection

jaise ek container mein paani hai

and we started supplying heat then jo molecules neeche present hai unki density km ho jayegi due to heat and buoyancy force bhi to laga to ye upr chle gye,

at the same time upr wale molecules ki density comparable jayada ho gyi therefore vo neeche aa jayenge or aise hi upr neeche chlta rahega

heat transfer heat convection k liye hi simple term hai

Answer 2

Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases.
