Question

explain convection and radiation with example

Answer 1

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.


Everyday Examples of Convection. Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.


In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation such as radio waves, visible light, and x-rays. particle radiation such as α, β, and neutron radiation.


Here are some examples of different types of radiation:

ultraviolet light from the sun.

heat from a stove burner.

visible light from a candle.

x-rays from an x-ray machine.

alpha particles emitted from the radioactive decay of uranium.

sound waves from your stereo.

microwaves from a microwave oven.
