Question

Draw a Venn diagram to show the similarities and differences between conduction,convection and radiation.

Answer 1

"Comparison between conduction, convection and radiation:

1. Both conduction and convection require a medium for heat transfer, but radiation does not require any medium

2. Conduction occurs by direct contact with objects, convection through liquids and radiation through vacuum

3. Both conduction and convection are slow processes, whereas radiation is a fast process

4. Both conduction and convection do not follows the laws of reflection and refraction but radiation does
