Let’s go through each image one by one and figure out what type of heat transfer is happening.
There are three main types of heat transfer:
-
Conduction – when heat moves through direct contact (like touching a hot pan).
-
Convection – when heat moves through fluids (liquids or gases) as they circulate (like hot air rising).
-
Radiation – when heat travels through space without needing matter (like the Sun warming your face).

1.
Hot water rises, cold water sinks
→ This shows water moving in circles because hot water is lighter and rises, while cold water sinks to get heated. That’s
convection.
2.
A camp fire
→ You feel warmth from the fire even if you’re not touching it or standing above it. The heat reaches you through invisible waves — that’s
radiation.
3.
Microwave oven
→ Microwaves use electromagnetic waves to heat food directly. That’s also
radiation.
4.
Holding mug feels hot
→ Your hand touches the hot mug, and heat moves directly into your skin. That’s
conduction.
5.
Egg cooking in a hot pan
→ The egg touches the hot pan, and heat moves from the pan to the egg. That’s
conduction.
6.
Heated air rises, cools, then falls
→ Air moves in a loop: warm air goes up, cools down, then sinks again. That’s
convection.
