Question

Name the modes of transfer of heat.
a) Conduction
b) Convection
c) Radiation
d) Reflection

Answer 1

Heat transfer is that the physical act of thermal energy being exchanged between two systems by dissipating heat. Temperature and therefore the flow of warmth are the fundamental principles of heat transfer.

Complete step by step answer:
a) Conduction: it's the transfer of warmth through physical contact. Conduction is the most vital kind of heat transfer within a solid object or between solids in thermal contact.
b) Convection: When a fluid, like air or a liquid, is heated then travels removed from the source, it carries the thermal energy along. This kind of warmth transfer is termed convection.
c) Radiation: it's the transfer of heat through electromagnetic energy. Radiation occurs through a vacuum or any transparent medium (either solid or fluid).
d) Reflection: it's a lightweight or sound energy transfer, not a heat transfer.

So, the correct answers are “Option A,B and C”.

Note:
The importance of heat transfer helps you to grasp the way to determine the method of heat which you're being exposed to like conduction, convection, and radiation.
examples of each of the subsequent are,
Conduction: Engine gets hot once the car is switched on, employing a heating bag we are able to warm our fingers
Convection: The steam from a steaming hot tea get transferred into the air, air conditioners also are an honest example of convection
Radiation: UV rays, heat from a stove burner, X-rays, microwaves.
