differentiate between Conduction and radiation in boxes
Answers
Answer:
In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles.

Answer:
ok
Explanation:
CONVECTION RADIATION
1. Medium is necessary for
transfer of heat.
Medium is necessary for
transfer of heat
No medium is required for
transfer of heat
2. Conduction is not possible
in vacuum
Convection is not possible in
vacuum
Radiation is possible in
vacuum
3. The particles of the
medium do not leave their
mean positions. They transfer
heat by vibrating about their
mean positions.
The particles of the medium
leave their mean position s
and move in upward direction
carrying heat from the source
The medium remains
unaffected
4. The transfer of heat can be
in any direction
The transfer of heat is only in
vertically upward direction
Transfer of heat is in all
directions along a straight
path
5. The process is slow The process is faster than
conduction
The process is the fastest and
transfer of heat takes place
with the speed of
3 x 108 m/s
