Q

Describe the arrangement and features of particles in a solid.

A

The particles in a solid are arranged in straight rows and do not move - only vibrate about their fixed positions. There are strong forces of attraction holding the particles together.

Q

Why does heat energy travel faster through metals than other materials?

A

Metals have free electrons therefore the electrons can move freely so heat is transferred much more quickly thorough the metal.
