Question

at lunch, the babysitter gives tanya and damien each a chocolate candy. tanya puts her candy on her plate damien saves his candy in his pocket. after lunch, damien discovers his candy has melted. which statement accurately compares the atoms in the two candies?
the atoms in damien’s candy have less energy.
the atoms in damien’s candy are vibrating faster
the atoms in damien’s candy are unable to move

Explanation:

To solve this, we analyze the effect of temperature on atomic motion. Melting occurs when heat is absorbed, increasing atomic energy. Damien’s candy melted (was in a warmer pocket), so its atoms have more energy and vibrate faster. The first option is wrong (less energy would not melt), the third is wrong (atoms in melted candy can move more). So the correct statement is about faster vibration.

Answer:

The atoms in Damien’s candy are vibrating faster
