Tell few examples from daily life where heat transfer by
conduction, convection and radiation is taking place List the
examples and identify the method of heat transfer in a tabular
form

Malka Tarannum · Accepted Answer

Conduction

Convection

Radiation

1) Any utensil when placed onto a
stovetop and when the stove is turned on, the utensil becomes very
hot due to the conduction of heat from the burner to the
utensil
1) When we heat a liquid in a flask, the
particles of the liquid at the bottom, get heated, become lighter
and actually rise up The cold liquid particles from above at lower
temperature being heavy come down due to gravity and receive the
heat The process is repeated In this way a convection cycle is set
up Infact, all fluids are heated by convection
1) When we stand near fire, we feel hot
as heat comes to us through radiation

2) When an iron is placed on a shirt to
be ironed, heat from the iron is conducted to the shirt, which
removes all the wrinkles from the shirt and make the shirt to look
sharp
2) In an air conditioner, the cooling feature is
placed at the top Thus, warm air rises up to the cooling feature,
it is replaced by cold air, and the room gets cooled
down
2) On a hot day, when a bicycle is left
in sunlight, after sometimes, it is found that the bicycle becomes
very hot due to the radiation of heat from the sun

3) When you place an ice cube in your
hand, the ice will start to melt due to the heat conducted from
your hand to the ice cube
3) During the day, the strong solar heat
warms the ground and the sea water The air in contact with the warm
ground is heated by conduction It expands and become lighter than
the surrounding air As a result, the warmer air rises and the
cooler air from above moves down to fill the space This creates a
sea breeze near a large quantity of sea water In this way, thermal
convection cycle is set up, which transfers heat away from the
ground
3) A solar cooker is a device which is
used to cook food by utilising the heat radiation coming from the
sun
