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.
Explanation:
CONDUCTION:-)
The definition of conduction is the movement of something such as heat or electricity through a medium or passage. An example of conduction is using a metal rod to roast marshmallows on an open fire and feeling the heat rise through the rod from the fire to your hand.
CONVECTION:-)
Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.
RADIATION:-)
Radiation is the process of sending off energy in the form of light, heat, x-rays or nuclear particles. An example of radiation are the energy waves off of a nuclear bomb.
