Pls explain with options,and why not other options
Dear Student
The correct option will be (b) Convection
conduction takes place in solids and the heat travels from hotter region to colder region but molecules do not move , they just transfer the heat as the molecules are in close contact with each other.
Convection takes place in liquids and hence heated molecules travels from hit to cold portion as there is some space between molecules.
In Radiation heat gets transfered without any contact between molecules.
