Question

while making tea over the burner when does the heat transfer occurs due to (a) Conduction (b) Convection​

Answer 1

∆ conduction

You pour a cup of steaming tea from a teapot. Your teacup is warm to the touch. Somehow, heat was transferred from one object (the cup) to another (your hand) that it was touching. This is an example of conduction, one of three ways that heat can be transferred

Answer 2

Heat transfer by conduction and convection is as follows -

• Conduction refers to transfer of heat on direct contact. When pan is kept over the lighted burner, the heat transfer takes place through conduction.

• Convection is the heat transfer by movement of warm molecules to the cooler areas, thus heating the cool molecules by making them close to heat source. When water is poured to prepare tea, the boiling takes place through convection.
