2. HEAT TRANSFER METHODS :-
Conduction :-
Conduction transfers heat via direct molecular collision.
Convection :-
When a fluid, such as air or a liquid,
is heated and then travels away
from the source, it carries the
thermal energy along.
Radiation:-
The emission of energy as electromagnetic waves or as moving
subatomic particles.
