Question

the alcohol particles gained heat as they turned into gas
question 3
what does the chocolate shell demo show about how solids change?
cold temperatures cause particles to slide past one another
adding heat causes particles to move more and lose their shape
removing heat causes particles to bounce farther apart
heat makes particles stick together and form a harder solid
when a solid melts or a liquid boils, it goes through a phase change - a transformation fr happen when a substance gains or loses enough thermal energy to rearrange the way it
if a substance absorbs enough heat, the particles move faster and farther apart, and it n
if a substance loses enough heat, the particles slow down and move closer together, and
we saved your progress a few seconds a

Explanation:

When heat is added to a solid (like chocolate in the demo), the particles gain energy. This increased energy makes the particles move more vigorously. As a result, the orderly structure of the solid (where particles are relatively fixed in position) breaks down. The particles can move more freely, and the solid loses its definite shape (melts). For example, cold temperatures keep particles in a more fixed, ordered state (like in a solid), but adding heat disrupts this. Removing heat would make particles slow down and come closer (like in freezing, not what the demo shows). And heat doesn't make particles stick together to form a harder solid (that would be the opposite of melting).

Answer:

Adding heat causes particles to move more and lose their shape.
