What is differnece between covention and conduction
Answers
Explanation:
Difference Between Conduction, Convection and Radiation. 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.
Topic :
"Transfer of Heat"
Heat :
Heat is the transfer of energy from a higher temperature to a lower temperature. Heat can be measured in Joules (J) and KJ (kilo Joules)
Heat can be transfer in three ways :
- Conduction.
- Convection.
- Radiation.
Difference between convention and conduction :
Conduction :
Heat can travel through solids. You will this if you have ever tried stirring the hot soup in a saucepan with a metal spoon. Heat (Thermal) energy flows quickly to the end of the spoon which can burn your fingers.
The moment of heat through a solid such as metal called "conduction".
Convection :
Liquids and gases may be poor conductors oh heat, but they can carry heat because their particles are free to move around.
When the water boiled in an electric kettle. The heating element in the kettle only warms the water touching it. Warm water is less dense than cold water So, the warm water rises. This process is called "convection".
