Conduction
The transfer of heat through a material by direct
contact.
Examples:
1. A metal spoon gets hot quickly in hot cocoa.
2. An iron heats up the material it comes in contact with.

Convection
The transfer of heat in a fluid (gas or liquid) as a
result of the movement of the fluid itself.
:
Note that the warm material rises, cools at the surface and
then sinks in a circular pattern.

Breath on a Cold Day: As the organism exhales,
water vapor in the breath comes in contact with
colder air. This causes water vapor to condense into
water droplets which we can see suspended in the
air. The heat from the organism’s breath warms up
the surrounding cooler air. The movement of matter
facilitates the transference of heat, so transfer is
by convection.

Steaming Hot Coffee: The hot coffee is at a higher
temperature than the surrounding air and mug. Heat is
transferred from the coffee to the mug/cooler air
above the coffee and we see the water droplets
condense by convection.

cream causing the ice cream to melt. The heat

Hot Spring Geyser: Hot springs are geothermal
heated groundwater. Cooler water seeps into the
ground and comes in contact with hot rocks
associated with magma chambers below the Earth’s
surface (conduction). As water is heated to above
boiling point, it remains in liquid form due to
intense pressure, but is much less dense, bringing it
to the surface. (convection)

Boiling Water: The pot becomes hot from touching
the heat source (conduction), the water at the
bottom of the pot gets warm first, and moves upward
since it becomes less dense. This pushes the cooler
water at the top down, creating a convection current.

Woodstove: Heat is transferred in two ways. Firelight
transfers heat by radiation, the woodstove becomes hot
due to conduction from the fire toughing the metal. The
air inside the stove gets hot, rising and falling in
a convection current. If you place an object on top of the
stove, you have another example of conduction.

Mirage: Heat from the sun warms the black asphalt
(radiation). The air directly above the asphalt becomes
hotter, drastically changing the density levels of air near
the ground. A wavy and often duplicate image appears
because light bends when it passes from one medium to
another (in this case: warmer air to cooler air).

Cooking in the Oven: Heat is transferred in an oven
primarily through convection and by radiation (from
heat being emitted from the hot walls. Convection ovens
are different from conventional ovens in that they
forcefully circulate the air.
