|
the transfer of heat in a liquid or gas by the upward movement of hot particles from one place to another
|
|
|
What is radiation?
|
the transfer of heat without the help of particles

|
Convection occurs in liquids and gases. Why?
|
because the particles are free to move from one place to another
|
|
|
Convection does not occur in solids. Why?
|
because the particles are closely packed together. They are not free to move from one place to another
