name the three modes by which heat is transmitted
Answers
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).
Explanation:
CONDUCTION:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart.
CONVECTION:
Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.
RADIATION:
The process of the transfer of the heat from one place to another place without heating the intervening medium is called radiation. For example, the heat from the sun reaches the earth through radiation mode. They can reflect and refract like light waves.
