Conduction

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through a medium without any flow of the medium.

Front

Which material is the best conductor of heat?

Back

Steel is the best conductor of heat.

Front

Which phase of matter is the best conductor of heat?

Back

Solid is the best conductor of heat.

Front

Why do metals conduct thermal energy more quickly?

Back

Metals conduct thermal energy more quickly due to the presence of free electrons.

Front

Why are gases poor conductors of electricity?

Back

Gases are poor conductors of electricity because particles are far apart and collisions are less frequent.

Front

What is the role of free electrons in thermal conduction?

Back

Free electrons facilitate the transfer of thermal energy by moving and colliding with other particles.

Front

How does temperature affect conduction?

Back

Higher temperatures increase the kinetic energy of particles, enhancing the rate of conduction.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as wood or plastic.

Front

Give an example of a good thermal conductor.

Back

Copper is an example of a good thermal conductor.

Front

What happens to the particles in a solid during conduction?

Back

In a solid, particles vibrate in place and transfer energy to neighboring particles.
