Heat by Convection

What is Convection?

• transfer of heat by movement of particles in a fluid.

• the transfer of heat between particles in a contact

• friction between 2 energies, that causes heat

When a fluid is heated, its particles move faster and farther apart, and it becomes less dense

• TRUE

• FALSE

the continuous circulation of the particles in a fluid as a result of convection

• convection current

• temperature

• conduction

the less fluid falls, and cooler fluid, wich is more dense, raises

• TRUE

• FALSE

Convection cannot take place in solids.

• True

• False

why convection cannot take place in solids?

• why not

• because their particles are in continous circulation

• because their particles can only vibrate in a place

the movement of particles due to differences in density within a fluid create....

• Heat Transfer

• Thermal Energy

• Convection currents

wich of the following statements is correct.

• particles of a warm fluid move faster, than a cool fluid

• Convection cannot take place in solids

• the heat transfer is the continuous circulation of the particles in a fluid

• all of them are correct
