Explain the three modes of tranfer of heat conduction convection and radiation
Answers
Answer:
Explanation:
____________
Conduction;
___________
Conduction is the phenomenon by which solids transfer heat energy to other solid.
It occurs by direct contact of solid.
It is occur so in solid because their particles are tightly compressed;
Ex-An hot piece of iron in contact with cool iron makes cool one hot;
Convection;
It is the process by which liquid or fluids sometimes in gases transfer heat energy or thermal energy.
The hot air or liquid moves down to dense particles making itself cool;
Ex-Clouds made by convection;
Radiation;
It is the transfer of energy with the help of waves especially electromagnetic waves;the waves used in radiation carries huge amount of energy or heat .Radiation is used in treatment of many diesaese like cancer etc
It can occurs in all three states;
Ex-Radiation therapy is used in Leukemia
