3 Methods of Heat Transfer.
Radiation: The transfer of energy by electromagnetic waves.
Transferred by electromagnetic radiation.
Examples:
1. Laying on the beach and feeling your face getting hot.
2. Heat from the sun warming the pool.
3. Putting the hand near the burner on an oven.
4. Feeling heat from a campfire.
5. Heating a tin can of water using Bunsen burner,
Conduction: The transfer of thermal energy through matter by the direct contact of particles called conduction.
Transferred by direct contact.
Examples
1. Your hand touching the stove.
2. The ice touching your hand and melting.
3. The tortilla burning will touching the pan.
4. Heat from the car when you touch it.
5. A metal pot touching a burner.
Convection: The transfer of energy in fluids by the movement of the heated particles.
Transferred by the mass motion of molecules.
Examples:
1. A ceiling fan forcing the warm air downward.
2. Boiling water moving in a circular motion.
3. Warm air put at the top and cooler air goes downward.
4. When heat moves to the ice from the air.
5. Hot Air Balloon.
