Pregunta 20 de 28

1

Usually conduction is faster in denser solids, because the particles are closer together and so will collide more often and pass energy between them. Materials that have larger spaces between their particles conduct heat energy much more slowly - these materials are insulators.

They have expensive electrons

Explicación

Pregunta 23 de 28

FALSO

Explicación

Pregunta 24 de 28

1

At the hot end of the metal, electrons will move: faster or slower?

Slower

Explicación

Pregunta 25 de 28

1

At the hot end of the metal, electrons will more faster and collide with other free electrons. What happens next?

Selecciona una de las siguientes respuestas posibles:

They transfer energy
They transfer electricity
They exchange Christmas cards

Explicación

Pregunta 26 de 28

1

Because the electrons can move freely, this is obviously a much faster way of transferring the energy through the metal than slowly passing it between jostling neighbouring atoms. This is why heat energy travels so fast through metals.

VERDADERO
FALSO

Explicación
