transferred by conduction, convection and radiation in ________ .
boiler furnaces
melting of
ice
condensation of steam in condenser
none of these
boiler furnaces
● Conduction is
the transfer of thermal energy through direct contact.
● Convection is
the transfer of thermal energy through the movement of a
liquid or gas.
● Radiation is
the transfer of thermal energy through thermal emission
In Boiler
furnace, heat is transferred by conduction, convection and radiation.
Hence, the
correct option is (A).
