Question

write 3 difference between radiation and conduction​

Answer 1

Answer:

Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.

Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven.

Answer 2

in radiation does not connection between two bodies but in conduction the body has to be connected in radiation the heat get transfer through the air in conduction heat get transfer in the form of wave the deviation is a slow process conduction is a fast process
