Define :- (a) Conduction (b) Convection
Answers
a) Conduction is defined as. The process in which heat flows from objects with higher temperature to objects with lower temperature. An area of higher kinetic energy transfers thermal energy towards the lower kinetic energy area.
b)When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.
Answer:
CONDUCTION : The definition of conduction is the movement of something such as heat or electricity through a medium or passage. ... In electrical conduction, energy is transferred by the movement of electrons or ions.
CONVECTION : Convection occurs when heat is transferred through a gas or liquid by the hotter material moving into a cooler area.
