Question

multiple choice listen what happens to particles in a solid when they are heated enough to become a gas? a they slow down their movement. b they remain still. c they shrink in size. d they vibrate faster and break free.

Explanation:

When a solid is heated to become a gas (a process called sublimation or melting - then boiling for most substances), the heat energy causes the particles to gain kinetic energy. This makes them vibrate faster and break free from their fixed positions in the solid structure.

Answer:

D. They vibrate faster and break free.
