Question

Sir/Ma'am

Can you give me the examples of conduction in liquid, solids and gases and convection in liquids and gases and also some examples of radiation.

Answer 1

Conduction:-
When ironing a skirt, the iron is hot and the heat is transferred to the skirt.
The heat from a hot liquid makes the cup itself hot.
Roasting wieners over a campfire is fun until the heat from the fire is conducted up the coat hanger to your hand.

Convection:-

• 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.
• Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
• Steaming cup of hot tea - The steam is showing heat being transfered into the air.
• Ice melting - Heat moves to the ice from the air. This causes the melting from a solid to liquid

Radiation:-

• Heat from the sun warming your face
• Heat from a lightbulb
• Heat from a fire
• Heat from anything else which is warmer than its surroundings.
